Will these stay up under a dress without rolling or riding up?

Yes. The seamless, one-piece construction means there are no raw edges or seams to curl, and the traceless waistband sits flush without digging in. The hem is cut with enough stretch to stay flat against the thigh through a full day of wear.

Do they fit throughout the whole pregnancy?

The one-size knit has significant four-way stretch and the high-waist U-panel is cut to accommodate a growing bump rather than sit below it. Most customers wear them from mid-pregnancy through to the final weeks, though fit will feel closer and more supportive as the bump grows. Postpartum wear is also fine once the panel sits comfortably.

Will the waistband leave a mark on my skin?

The waistband is seamless and traceless with no exposed elastic or hard edge. As with any fitted waistband worn close to the skin for long periods during pregnancy, there may occasionally be a light temporary impression, but it is not designed to compress or dig in.
