Learn what to look for in a bodysuit—from fabric blends to fit features like snap gussets and seamless construction. This guide helps you choose the best bodysuit for your outfits.
Quick answer
Focus on fabric blend for comfort and longevity, and on construction details like a snap gusset and seamless design for a stay-tucked fit that works under any outfit.
Why fabric blend matters most
The fabric determines how a bodysuit feels, stretches, and lasts. A modal blend (like 79% modal with elastane) offers a soft, almost buttery hand feel and excellent drape, making it a great first layer. Microfiber blends (nylon/elastane) are more matte and durable, holding their shape wash after wash. Italian microfiber blends add breathability and are often used in styles meant to be seen on their own.
A higher elastane percentage (around 21-22%) means more stretch and recovery, which helps the bodysuit stay snug without sagging. Lower elastane (12%) still allows movement but may not compress as much. Your choice depends on whether you want a soft, barely-there layer or a more structured top.
Construction details that define fit
Look for a snap gusset at the bottom. This lets you use the restroom without fully undressing—a practical feature that makes bodysuits more wearable for long days. A raw-cut thong bottom eliminates visible panty lines (VPL) and keeps the silhouette smooth under leggings or slim skirts.
Seamless construction is key for a no-show look under fitted tops. It also reduces chafing and gives a second-skin feel. Some bodysuits include thumbholes, which help keep sleeves in place under a jacket and add a modern styling detail.
Your bodysuit decision rules
- Check the fabric blend: Modal blends (like 79% modal with elastane) = soft, drapey, great for layering. Microfiber blends (nylon/elastane) = matte, durable, holds shape. Italian microfiber = breathable, long-lasting, good for standalone wear.
- Look for a snap gusset: A snap gusset at the bottom lets you use the restroom without taking the bodysuit off. This is a must for all-day wear and convenience. If a bodysuit lacks a snap gusset, it's less practical for daily use.
- Prioritize seamless construction: Seamless bodysuits reduce chafing and create a smooth silhouette under fitted clothing. They also feel like a second skin, which adds to comfort. For a no-show look under tight tops, seamless is non-negotiable.
- Consider the neckline and sleeve options: Crewneck tanks are versatile for layering. Turtlenecks add warmth and style. Short sleeves balance coverage and breathability. Choose based on your wardrobe gaps.
Bodysuits we recommend
- Butter Crewneck Tank Bodysuit: Made from a luxury Austrian modal blend (79% modal, 21% elastane) with a seamless raw-cut thong bottom and snap gusset. This is an ideal first layer—the modal feels soft against skin, the high stretch ensures a comfortable fit, and the raw-cut thong eliminates VPL under any bottom.
Butter Crewneck Tank Bodysuit - Ballet Short Sleeve Turtleneck Bodysuit: Crafted from a luxe European microfiber blend (87% nylon, 12% elastane, 1% cotton) with a seamless, stay-tucked fit. The matte microfiber finish makes this turtleneck a versatile piece that can be tucked into high-waisted pants or worn alone, and it holds its shape well for all-day wear.

Who should buy which bodysuit
Best for
- Anyone wanting a soft, barely-there first layer under blouses or sweaters
- Those who prioritize a no-VPL silhouette for leggings or slim skirts
Not for
- If you prefer a structured, compressive top that holds you in, a modal bodysuit may feel too soft—consider a microfiber blend instead
- If you dislike thong-style bottoms, look for bodysuits with a full-coverage bottom (though most seamless styles use a thong to avoid lines)
