# NULAYER Fit Guide

## Pages
- [Can you eat in shapewear?](https://nulayerfit.com/answers/can-you-eat-in-shapewear/): Yes, in medium-firm and in the right size. The NULAYER bodysuit is built to be comfortable to sit and eat in. If a meal hurts, it is the size or the compression level, not you.
- [Can you pee in a shapewear bodysuit?](https://nulayerfit.com/answers/can-you-pee-in-a-shapewear-bodysuit/): Yes, if the bodysuit opens at the crotch. NULAYER's has a hook-and-eye closure there, the same hooks as a bra band, so you unhook, go, and hook it back without pulling the bodysuit down or undressing.
- [Can you wear your own bra with a shapewear bodysuit?](https://nulayerfit.com/answers/can-you-wear-your-own-bra-with-a-shapewear-bodysuit/): Yes. The built-in bra has no compression on the bust, so your own bra goes underneath, its straps under the bodysuit straps. Wear one for more support than the built-in bra gives. A strapless dress is a different question.
- [Does NULAYER run small? Sizing and between sizes](https://nulayerfit.com/answers/does-nulayer-run-small/): No. NULAYER is true to size for most wearers, measured by bust and waist on the chart. The exceptions are the edges: at the top of a band go one up, and a long torso often means going up.
- [How long can you wear shapewear in a day?](https://nulayerfit.com/answers/how-long-can-you-wear-shapewear-in-a-day/): All evening, or a full day, in medium-firm and in the right size. Ours has breathable mesh panels and a hook-and-eye crotch closure for the bathroom. If anything hurts or goes numb, take it off.
- [How tight should shapewear be?](https://nulayerfit.com/answers/how-tight-should-shapewear-be/): Snug, not painful. You should breathe all the way in, sit and eat a meal. Medium-firm smooths the waist and midsection without squeezing. Pinching, or straps that pull at their longest, means too small; a drifting panel means too large.
- [How to put on a shapewear bodysuit](https://nulayerfit.com/answers/how-to-put-on-a-shapewear-bodysuit/): Step in from the bottom, pull it up to the waist, hook the hook-and-eye crotch closure, straps over the shoulders, adjust for your torso. Do it standing. The first time takes longer; after that it is quick.
- [How to wash a shapewear bodysuit](https://nulayerfit.com/answers/how-to-wash-a-shapewear-bodysuit/): Machine wash cold and hang dry, as the care label says. Hook the crotch closure first so the hooks do not catch, and use a lingerie bag. No tumble dryer, no bleach, no iron: heat wears out a spandex knit.
- [Is shapewear see-through under a white dress?](https://nulayerfit.com/answers/is-shapewear-see-through-under-a-white-dress/): It depends on the shade, not the compression. Under white or ivory wear Beige, never Black. Beige is one light tone, so do a daylight mirror test at home; under a very sheer white, anything can shadow through.
- [Thong or mid-thigh: which bodysuit cut?](https://nulayerfit.com/answers/thong-or-mid-thigh-shapewear/): Thong under anything that clings below the hip: satin, bodycon, jersey. Mid-thigh when the dress falls loose from the hip and you want the upper thigh smoothed, or under jeans and trousers. Same top half, same closure, same price.
- [Shapewear that doesn't roll down when you sit](https://nulayerfit.com/concern/shapewear-that-doesnt-roll-down/): A bodysuit is the cut that does not roll, because the straps hold the waist from above. The adjustment is the straps: set them for your torso length, and if they pull at their longest, the size is one band too small.
- [Shapewear for a backless dress](https://nulayerfit.com/fit/backless-dress/): No. A truly backless dress shows the NULAYER bodysuit's straps and back. We do not have a backless version yet. For a dress that is low-back rather than backless, read the second section before deciding.
- [Shapewear for a bodycon dress](https://nulayerfit.com/fit/bodycon-dress/): Yes. Wear the thong cut, Black under a dark dress and Beige under a light one, straps set for your torso. A bodycon dress shows every edge, so the bonded edges and the thong back matter more than compression.
- [Shapewear for a satin slip dress](https://nulayerfit.com/fit/satin-slip-dress/): Yes. Wear the thong cut in the shade closest to your skin, straps set for your torso length. Satin shows every seam and line, so the bonded edges and the thong back are what make this work, not compression.
- [Shapewear for a sequin dress](https://nulayerfit.com/fit/sequin-dress/): Yes. Wear the thong cut, Black under most sequin dresses, straps set for your torso. Most sequin dresses are lined and heavier than satin, so they hide more; the bodysuit's job is the waist line and no panty line.
- [Shapewear for a strapless dress](https://nulayerfit.com/fit/strapless-dress/): No. The NULAYER bodysuit has shoulder straps, and under a strapless dress they show. Do not tuck them. We do not make a strapless or convertible version yet. Wear a strapless bra with a high-waisted smoothing brief or short instead.
- [Shapewear under a white or ivory dress](https://nulayerfit.com/fit/white-or-ivory-dress/): Yes, with one adjustment: Beige, never Black. Our Beige is a light beige, so under a very sheer white dress check it in daylight first. Thong under a clinging white dress; mid-thigh only under a loose skirt.
- [Shapewear for a wrap dress](https://nulayerfit.com/fit/wrap-dress/): Yes. Either cut works. Set the straps so the bodysuit's deep V sits lower than the wrap's V; the waist tie then lands over the smoothed panel. The mid-thigh works here because the skirt falls loose from the hip.
- [Shapewear for a holiday party](https://nulayerfit.com/occasion/holiday-party/): Yes. December parties mean sequins and velvet, a coat on and off, standing, sitting and eating. Wear the thong in Black under a dark party dress, straps set so the deep V sits under the neckline.
- [Shapewear for a wedding guest](https://nulayerfit.com/occasion/wedding-guest/): Yes. A wedding is six to eight hours with a meal, dancing and a bathroom queue. Wear the medium-firm bodysuit you can eat in, with the hook-and-eye crotch closure for the queue. Cut by dress; straps set at home.
- [Size 2XL–3XL](https://nulayerfit.com/size/2xl-3xl/): 2XL–3XL is our largest band in stock: US 16–20, bust 41.5 to 48 inches, waist 35 to 41.5. Both cuts and both shades come in it. Above the range, we are not there yet.
- [Size L–XL](https://nulayerfit.com/size/l-xl/): L–XL covers US 12–14: bust 39 to 41 inches, waist 31.5 to 34.5. It is the narrowest band on the chart, so measure before you order. At bust 41 or waist 34.5, go up to 2XL–3XL.
- [Size S–M](https://nulayerfit.com/size/s-m/): S–M covers US 4–10: bust 34 to 38.5 inches, waist 26.5 to 31. Both cuts and both shades come in it. At the top of the range, go up to L–XL for comfort; our listing model does.
- [Size XXS–XS](https://nulayerfit.com/size/xxs-xs/): XXS–XS is our smallest band: US 0–2, bust 30 to 33.5 inches, waist 23 to 26. Both cuts and both shades come in it. Below the range, the bodysuit may sit loose rather than smooth.
- [Shapewear for a long torso](https://nulayerfit.com/torso/long-torso/): Lengthen the straps. They are fully adjustable; set them until the hook-and-eye crotch closure sits comfortably and the waist panel is at your natural waist. If the longest setting still pulls, go up a band, whatever the chart says.
- [Shapewear for a short (petite) torso](https://nulayerfit.com/torso/petite-torso/): Shorten the straps; they are fully adjustable. Stop when the waist panel sits at your natural waist, not the ribs, and the hook-and-eye crotch closure is comfortable. Keep your bust-and-waist size; do not size down to fix torso length.
