Skims XS vs. Small: Which size is right for you?

Choosing between an Extra Small (XS) and a Small from Skims can be tricky, as the main difference is the level of compression and fit on the body. An XS is designed for a very snug, body-hugging silhouette with maximum shaping (typically fitting busts of 32-34", waists of 24-26", and hips of 34-36"), while a Small offers a slightly more relaxed, yet still form-fitting and smooth, experience for those with slightly larger measurements (busts 34-36", waists 26-28", hips 36-38").

Here's everything you need to know to find the right Skims size for your body and preferred fit.

Skims Size XS

The Skims Extra Small (XS) size is engineered for those with petite frames or individuals who desire the highest level of compression and a sculpted, second-skin fit. Because Skims' fabrics are famously stretchy, the XS relies on a tighter cut to create its signature shaping effect. It's intended to feel snug and highly supportive.

• What it is: Skims' size category designed for a tight, compressive, and body-contouring fit.
• Measurements: Typically corresponds to a bust of 32-34 inches, a waist of 24-26 inches, and hips of 34-36 inches.
• Sizing/Fit: A true-to-size fit for those with measurements at the lower end of the brand's size chart. Offers significant compression, which can feel restrictive to some but provides a highly sculpted look.
• Pros: Provides maximum shaping and a sleek silhouette. Ideal for a pronounced body-hugging look. Conforms closely without excess fabric on petite frames.
• Cons: May feel too tight or restrictive for comfortable all-day wear. Not ideal if your measurements fall on the cusp of a Small and you dislike compression.

This size works well for those with petite measurements or anyone prioritizing a highly compressive and sculpted look over everyday comfort.

Skims Size Small

The Small is one of the most common size categories at Skims, designed to offer a form-fitting and smoothing look without the intense compression of an XS. It provides enough room for comfort and movement while still delivering the sleek, seamless appearance the brand is known for. This size is often the go-to for customers who are in-between sizes or who prioritize all-day wearability.

• What it is: A popular size that offers a balance of form-fitting sleekness and comfort.
• Measurements: Generally fits busts of 34-36 inches, waists of 26-28 inches, and hips of 36-38 inches.
• Sizing/Fit: Provides a close fit that smooths and contours but allows for more ease of movement than the XS. It accommodates a broader range of body shapes comfortably.
• Pros: Offers great all-day comfort. Provides a natural, smooth silhouette. A more forgiving fit for those whose measurements fluctuate or fall between sizes.
• Cons: Lacks the intense, sculpted compression of the XS size. May have slightly more fabric on very petite frames.

This size is a great option for individuals with average measurements right in the Small range or for those just slightly above XS who want a less constrictive feel.

Skims XS vs. Small Comparison

Fit & Measurements

The core difference between the Skims XS and Small lies in a 2-inch variance across key measurements. The XS is tailored for a bust of 32-34", waist of 24-26", and hips of 34-36". This creates a fit that is intentionally tight and sculpting.

The Small size category accommodates a bust of 34-36", waist of 26-28", and hips of 36-38". That extra room is designed to provide a comfortable, body-skimming fit rather than a compressive one. If your measurements are on the cusp - like a 26" waist - your choice will fully depend on how much compression you want.

Fabric & Compression

Both sizes use the same signature Skims fabrics, renowned for their softness and stretch (typically a blend of nylon and elastane). However, the fit makes the fabric perform differently. On an XS frame, the material is pulled taut, maximizing its compressive properties to create that "snatched" effect.

In a size Small, the fabric has slightly more give. It smooths and contours but doesn't squeeze as tightly. This gentle hold makes it more suitable for comfortable loungewear or subtle, everyday shaping under clothes.

Comfort & Wearability

Comfort is a huge factor in deciding between these two sizes. An XS might look amazingly sleek for an event or a photo shoot, but could feel restrictive after several hours of wear, especially for active movement. The compression is noticeable.

A Small is much better suited for all-day wear. It moves with your body more easily, making it a more practical choice for daily activities, from working at a desk to running errands. If all-day comfort is your goal, a Small is almost always the better option, especially if you are close to the size measurements.

Which One Should You Choose?

The right choice comes down to your personal measurements and how you want your clothes to feel.

Choose the XS if:

• Your measurements align perfectly with the XS specifications (waist 24-26" and below).
• You are looking for maximum compression and a highly sculpted, body-con fit.
• You have a petite frame and find that Small sizes often have excess fabric.
• You are buying a more compressive item, like from the Sculpting collection, and want its full effect.

Choose the Small if:

• Your measurements fall into the Small range (waist 26-28" etc.) or you are between an XS and Small.
• You prioritize comfort and all-day wearability over intense shaping.
• You prefer a piece that smooths your silhouette without feeling restrictive.
• You're buying from a very stretchy collection like Fits Everybody and want a comfortable, forgiving fit.

Frequently Asked Questions

What’s the main difference between Skims XS and Small?

The main difference is the fit and compression level. XS is designed for smaller measurements (e.g., a 24-26" waist) and offers a tight, highly compressive feel for maximum shaping. The Small is for slightly larger measurements (e.g., a 26-28" waist) and provides a comfortable, smooth fit with less compression.

Should I size up or down in Skims?

It depends on the collection and your fit preference. For collections like Sculpting, sticking to your true size based on the Skims size chart is best, as it's designed for compression. For softer loungewear or stretchy collections like Fits Everybody, you have more flexibility. Sizing down will create a more body-hugging fit, while sizing up will be more relaxed.

What if I am between an XS and a Small?

If you are in between sizes, choose based on your desired fit. Select XS if you want more compression and a "held-in" feeling. Choose Small if you prefer more comfort and a less constricting fit for everyday wear.

Are Skims sizes true to size?

Yes, Skims items are generally true to size according to their specific size chart. However, because they are designed to be form-fitting basics and shapewear, they can feel tighter than clothing from other brands. Always check your measurements against their chart before buying.

Does the fit differ across Skims collections?

Absolutely. The fit can feel very different depending on the collection. The Sculpting collection is very compressive and will feel much tighter than the ultra-stretchy and soft Fits Everybody collection, even in the same size. Always consider the fabric and intended purpose of the garment.

Will a Small be too loose if I usually wear XS in other brands?

Not necessarily. Because Skims is designed for a close fit, a Small will likely still be form-fitting and smoothing, not loose or baggy. It will simply have less noticeable compression than an XS.

Do Skims items stretch out over time?

Skims garments are made with high-quality materials including elastane, which ensures they retain their shape well after multiple wears and washes. While they will mold to your body, they are not known for stretching out permanently.

Which size is better for shapewear?

For shapewear, the choice depends on the level of sculpting you need. The XS will offer a higher level of compression for a more dramatic result. The Small will offer light to medium smoothing, which can be more comfortable for wearing several hours at a time, such as to a wedding or event.
