NULAYER › Answers › Can you eat in shapewear?
Your waist changes through a meal. It is smaller when you sit down hungry and larger by dessert, and a garment that holds the waist has to allow for that. A maximum-compression garment is designed to hold a fixed measurement; it does not give, so the meal pushes against it and the evening becomes about the waistband. That is the category of shapewear people mean when they say they could not eat in it.
The NULAYER bodysuit is medium-firm. It smooths the midsection and waist and it is built to be comfortable to sit and eat in. The fabric is 78% nylon, 22% spandex, with breathable mesh panels; in the right size it moves with a meal instead of against it. It is not a maximum-compression garment, and this is the reason we say so on every page: the trade for a bodysuit you can eat in is that it smooths rather than cinches.
Do two tests at home the week before. First, sit for ten minutes in the bodysuit with the dress on, on a dining chair rather than a sofa, and then stand up. The waist panel should be where you left it and nothing should have dug in. Second, eat a proper meal in it. Not a snack: the meal you would eat at the wedding, with a drink. If you finish the meal and forget you are wearing it, the size is right.
If the sit test is fine and the dinner test is not, you are between sizes and on the smaller side of it. The chart's rule is the smaller band for maximum smoothing and the larger for all-evening comfort. A seated dinner is the case the larger band was written for.
A wedding guest sits through a ceremony, stands for drinks, sits for a dinner of three courses and then dances. A holiday party is four hours of standing, plates and a coat that goes on and off. Both are long, both involve food, and both are what medium-firm is for. If the bodysuit hurts after you eat, the answer is not to eat less. It is a size too small, or you bought a maximum-compression garment for a job it was never right for. Change the size, or the garment. Not the dinner.
Which size: Size by bust and waist from the chart; if the event is a seated dinner and you are between sizes, take the larger band.
| Band | US | Bust (in) | Waist (in) |
|---|---|---|---|
| XXS–XS | 0–2 | 30–33.5 | 23–26 |
| S–M | 4–10 | 34–38.5 | 26.5–31 |
| L–XL | 12–14 | 39–41 | 31.5–34.5 |
| 2XL–3XL | 16–20 | 41.5–48 | 35–41.5 |
True to size for most wearers.

No. The hook-and-eye crotch closure is for the bathroom, not for relief. If you feel the need to loosen anything after a meal, the band is too small; go up one.
It smooths the waist and midsection and stays flat through a meal. If you want to be pulled in hard for photos and do not plan to eat, you want a firmer garment than this one.
No. The waist panel and the compression are the same in both cuts. The mid-thigh adds coverage on the thigh, not tightness at the waist.
