This is the one style in the Shapewear collection that doesn't use single-letter sizing — worth a dedicated look so it doesn't get ordered the same way as everything else.
Quick answer
The Zip-Up Corset Waist Trainer ($35.51) sizes in combined ranges — XS/S, M/L, XL/2XL, 3XL/4XL — rather than single sizes like the rest of the collection. Measure your natural waist (see our sizing guide) and match to the range your measurement falls within, not a single letter.
Why combined-range sizing exists here specifically
The front zipper (instead of a back closure) already allows some fit adjustment on its own, which is likely why this style uses broader combined ranges — the zip mechanism itself absorbs some of the fit variation that a fixed single size would need to cover alone.
What to do if you're between two ranges
Since each range already spans two sizes, being at the edge of a range is less common than with single-size styles — but if you are right at the boundary, size up to the next range for comfort, same general rule as the rest of the collection.
The color options
This style comes in both Black and Brown, more color variety than most of the single-size shaping styles in the collection.
FAQ
Is the zip-up style easier to get in and out of than the others?
Yes — the front zipper is faster than styles relying only on hook-and-eye closures, which is part of its appeal for a corset-style waist trainer.
Does the zipper affect durability?
A quality zipper is generally durable with normal use — avoid forcing it if it catches, and address any snag immediately rather than continuing to pull.
The bottom line
Measure your natural waist and match to the correct combined range, not a single letter size. See the Waist Trainers & Shapewear collection for current availability.
