SKIMS and Spanx are the two names that come up every time someone asks me about shapewear or bodysuits. They dominate search results, they dominate social media, and they both have passionate fans who swear one is vastly better than the other. After testing both extensively, I have a clear answer – but it depends entirely on what you're buying.
Before I get into it, a few related reads: my full SKIMS bodysuits review goes deeper on fit and fabric across specific styles, and my Rent the Runway review is worth reading if you're considering renting designer pieces to style over shapewear.

SKIMS vs Spanx: What Are They?
SKIMS is Kim Kardashian's shapewear and loungewear brand, launched in 2019, known for its inclusive shade range, bodysuits, and seamless construction across a wide range of silhouettes. Spanx is the original shapewear brand, founded in 2000, and remains the dominant name in smoothing undergarments, leggings, and shaping shorts. Both brands now compete across similar categories but with meaningfully different approaches to fit, fabric, and use case.
The Short Answer
SKIMS wins for bodysuits, loungewear, and everyday wear. Spanx wins for traditional shapewear – shaping shorts, high-waist briefs, and smoothing undergarments worn under fitted dresses. If you're buying shapewear to wear under a dress or pants, buy Spanx. If you're buying a bodysuit or something you'd wear as a visible part of your outfit, buy SKIMS.
Quick Takeaways
- SKIMS leads on bodysuits, lounge, and fabric softness
- Spanx leads on traditional shapewear compression and smoothing
- SKIMS has a significantly wider shade range for deeper skin tones
- Spanx runs smaller – size up from your usual when ordering
- SKIMS pricing is generally 10–20% higher than comparable Spanx styles
- Both offer free returns, but SKIMS restocks limited styles – buy when you see your size
What Is SKIMS?
SKIMS launched in 2019 under Kim Kardashian and immediately disrupted a shapewear market that had barely changed in 20 years. The brand's original selling point was a wide, inclusive shade range – 9 shades at launch, now expanded – that was designed to match a broader range of skin tones than anything previously available.
The product line has grown well beyond shapewear. As of May 2026, SKIMS sells bodysuits, bras, underwear, loungewear, swimwear, and a growing menswear line. The bodysuit category – particularly the Cotton Jersey and Fits Everybody styles – is where the brand has built its strongest reputation.
Price range: $28 for basics up to $128 for full-coverage bodysuits. Midrange for the category. See my detailed SKIMS bodysuits review for specific style breakdowns.
What Is Spanx?
Spanx is the brand that essentially created the modern shapewear category. Founder Sara Blakely cut the feet off her pantyhose in 2000 and turned that idea into a billion-dollar company. For over 20 years, Spanx has been the answer to "what do I wear under a tight dress."
Spanx's core products are still smoothing shorts, high-waist briefs, tights, and shaping bodysuits built around compression. They've expanded into leggings (the Faux Leather Leggings and Perfect Pant are cult items) and more casual styles, but compression shapewear remains the backbone of the brand.
Price range: $24 for basics up to $98 for compression bodysuits. Slightly lower than SKIMS at comparable coverage levels.
How Did I Test Both Brands?
I tested both SKIMS and Spanx across six specific product categories over three months in early 2026: shaping shorts, high-waist briefs, bodysuits, leggings, loungewear, and bras. I wore each product for full days in real conditions – at work, on dates, and on LA days where heat is a real factor in how comfortable shapewear feels.
I tested sizes across both brands. Spanx runs notably smaller than SKIMS – I needed to size up by one in every Spanx style I tried compared to my usual size. SKIMS runs true to size in most styles with the exception of the Fits Everybody line, which runs slightly small in the waist.
I also took note of wash durability. Both brands held up well after 10+ washes, with SKIMS fabrics maintaining their softness slightly better than Spanx over repeated washing.
Fabric, Fit, and Construction
SKIMS uses mostly nylon-spandex blends in their signature Fits Everybody fabric and a cotton-modal blend in their Cotton line. The Fits Everybody fabric is extraordinarily soft – it's the first thing people notice when they try SKIMS. It feels like a second skin rather than compression garment.
Spanx uses higher-compression nylon-spandex in their shapewear core and a different, softer blend in their leggings and lifestyle pieces. The compression in Spanx shapewear is noticeably firmer than anything in the SKIMS line – that's intentional and it's the point. If you need real smoothing under a form-fitting dress, Spanx delivers compression that SKIMS simply doesn't match.
Where SKIMS wins on construction is seam placement. The Fits Everybody bodysuits and shorts are designed to be visible – seamless edges, thoughtful lines that don't show through clothing. Spanx shapewear is invisible under clothing but not always comfortable to wear as its own layer.
Shade Range and Inclusivity
SKIMS was built on shade range inclusivity – it's a core brand value, not an afterthought. Current offerings span from Marble (lightest) through Onyx (deepest), with 9 dedicated nude shades. For women with medium to deep skin tones, SKIMS is the clear leader. The nudes actually read as nude across a wider range of skin tones than any comparable brand.
Spanx has improved their shade range significantly since SKIMS entered the market – they now offer more options than they did in 2020. But they still lag behind SKIMS, particularly at the deeper end of the spectrum. For light to medium skin tones, the difference is minimal. For deeper skin tones, SKIMS is the obvious choice.

Who Should Buy Which Brand?
Buy SKIMS if: you want bodysuits as part of your actual outfit, you have a medium to deep skin tone and need real nude options, you prioritize softness and everyday comfort, or you're shopping for loungewear that looks elevated enough to go outside in.
Buy Spanx if: you need firm compression under a fitted dress or pants, you're looking for shaping shorts or high-waist briefs specifically, or you want the Faux Leather Leggings or Perfect Pant (two of the most consistently praised items in either brand's catalog).
Own both if: you have a full wardrobe with both casual and formal needs. Most women who invest in one end up adding the other. SKIMS covers the everyday; Spanx covers the occasions. Pair either with a date night outfit or work looks and the difference in use case becomes obvious immediately.
Mistakes to Avoid When Buying Both
Ordering your usual size in Spanx. Almost everyone who complains that Spanx is uncomfortable ordered the wrong size. Spanx runs small. Size up one from your usual for shapewear and two sizes for their compression tights.
Buying SKIMS expecting firm compression. SKIMS is not a compression brand. If you need to smooth a silhouette under a tight evening dress, SKIMS Fits Everybody shorts will not do the job the way Spanx Higher Power shorts will. Understand what you're buying before you order.
Washing either brand in hot water. Both brands' fabrics are heat-sensitive. Hot water breaks down the spandex content and reduces elasticity. Wash cold, lay flat or hang to dry. Never put either brand in the dryer on high heat.
Waiting on SKIMS limited drops. SKIMS frequently releases limited-edition colorways and styles that sell out and don't restock. If you see your size in a style you want, buy it. They also run sales around major holidays – worth waiting for if you're not in a rush.
Frequently Asked Questions
Is SKIMS actually better than Spanx?
For bodysuits and everyday wear, yes. For traditional shapewear compression, no. SKIMS makes more comfortable, aesthetically designed pieces you'd wear as part of an outfit. Spanx makes more effective smoothing garments you wear under an outfit. The right answer depends on what you're buying.
Why is SKIMS so expensive?
SKIMS prices are higher than many competitors but not dramatically so for the category. You're paying for the brand's proprietary fabric development, inclusive shade range production, and celebrity branding. Whether that's worth it depends on what you prioritize. The Cotton Jersey basics at $28–$34 are competitively priced; the premium Fits Everybody bodysuits at $68–$128 are a genuine luxury purchase.
Does SKIMS run small?
Generally true to size, with exceptions. The Fits Everybody line runs slightly small in the waist for curvier body types. The Cotton line runs true. When in doubt, use SKIMS's size chart rather than your usual size – their measurements are specific and accurate if you measure yourself first.
Is Spanx comfortable for all-day wear?
The shapewear line – shaping shorts, high-waist briefs – is designed for strategic wear, not full-day lounging. For a three-hour dinner or a full workday at a desk, most people find it manageable. For a 10-hour day on your feet, compression shapewear of any brand becomes uncomfortable. Spanx's leggings and casual line are genuinely all-day comfortable; their core shapewear is more of an occasion piece.
Can SKIMS bodysuits be worn without a bra?
Depends on the style. The built-in bra styles (specifically the Fits Everybody Scoop Bodysuit and the Seamless Sculpt line) provide light support that works for smaller cup sizes without a separate bra. For larger cup sizes, a separate bra is recommended. SKIMS clearly labels which styles have built-in support on their product pages.
Which brand is better for plus sizes?
SKIMS. They carry sizes up to 4X across most of their core styles, and their fabrics are specifically developed to stretch and recover well across a wide size range without bunching or rolling. Spanx also carries extended sizes but the range is more limited and the fit reviews from plus-size customers are more inconsistent.
Is there a SKIMS dupe worth buying?
Several brands make SKIMS-adjacent pieces at lower price points – Naked Wardrobe and Amazon's own SKIMS-inspired basics are frequently mentioned. The fabric quality is noticeably lower but the basic bodysuit shapes hold up reasonably well for occasional wear. If you want to try the silhouette before investing in SKIMS, a dupe is a reasonable test. But for daily wear, the real thing holds its shape and softness significantly longer.
What is Spanx's best product?
The Higher Power High-Waisted Shorts are the product most often cited as a must-have. They provide genuine compression without rolling down at the waist – a problem that plagues many shapewear shorts. The Faux Leather Leggings are the brand's best lifestyle piece. Both are worth the investment and have been consistent best-sellers for years.
Does SKIMS go on sale?
Yes – SKIMS runs sales around Black Friday, Cyber Monday, Valentine's Day, and occasionally mid-season. Their sale section is permanent on the website and often has core styles at 20–40% off. Sign up for their email list for early sale access. Limited-edition styles rarely go on sale, so if you want something from a collab or seasonal drop, buy at full price when it launches.
Which is better for wearing under white clothing?
Neither brand's white or light styles are truly invisible under white clothing – this is a sheer-fabric problem that affects every shapewear brand. For under white, your best option from either brand is a shade matched to your skin tone, not a white garment. SKIMS's broader shade range gives them the edge here for most skin tones. Go one shade darker than you think you need – it reads more nude under sheer fabric.
Final Thoughts
SKIMS and Spanx are not competing for the same purchase. SKIMS built a brand around feeling good in what you wear. Spanx built a brand around wearing something under what you wear. Those are genuinely different needs, and understanding which one you're solving for is the whole decision.
If I'm getting dressed for a dinner or an event and I need a smooth silhouette under a fitted dress, I reach for Spanx. If I'm putting together an outfit that includes a bodysuit as a visible layer – which in LA is a reasonable choice for most of the year – I reach for SKIMS. Both are in my drawer. Both earn their place.
At Layers of Beauty, confidence always starts with understanding what you actually need rather than buying what looks good on a model. The right shapewear or bodysuit is the one that does its job without making you think about it all day. That's the standard worth shopping to.
