Most shapewear disappointments come down to one of three things: wrong size, wrong compression level, or wrong garment for the purpose. Here is what to know before you buy.
Sizing: the most important decision
Shapewear sizing does not always match your regular clothing size. Most shapewear brands size by weight and measurements rather than dress size. Before buying, measure your waist, hips, and if relevant, your thighs. Compare these measurements to the brand’s size chart not to your clothing size.
When you are between sizes, go up. Shapewear that is one size too small does not give you better compression it gives you discomfort, visible bulging above the garment edge, and a garment you will not want to wear. Shapewear that fits correctly feels firm and supportive. It should require some effort to put on, but once on, it should feel comfortable enough to wear for several hours.
Compression level: match it to your purpose
Everyday shapewear provides 15-20 mmHg appropriate for aesthetic smoothing under clothing. Post-surgical garments provide 40-50 mmHg for Stage 1 recovery. Choosing medical-grade compression for everyday wear is unnecessarily restrictive. Choosing everyday compression for post-surgical recovery is insufficient.
Coverage: match it to what you are wearing
Think about the outfits you plan to wear the shapewear under. High-waist briefs work under most dresses and trousers. A bodysuit eliminates waist gaps under fitted tops. Shaping shorts smooth the thigh area that briefs leave uncovered. Buying a garment that does not cover the area you want to smooth is a common and avoidable mistake.
Fabric and construction
Look for nylon-spandex blends with moisture-wicking properties for all-day comfort. Check that seams are flat-lock construction raised seams create pressure points and visible lines under clothing. A wide, reinforced waistband prevents rolling. If the waistband is narrow elastic, expect it to roll within a few hours of wear.
Questions to ask before buying
- Does it cover all the areas I want to smooth?
- Is the compression level appropriate for my purpose?
- Have I measured and checked the size chart rather than going by clothing size?
- Is the fabric breathable enough for how long I plan to wear it?
- Are the seams flat and smooth at stress points?
Answering these questions before purchasing dramatically increases the chance that your shapewear will actually do what you want it to do.
