They tend to really ride down low in the front. Like "let's censor bar this image" low. This makes the lining shift so far back as to be pointless, and they tend to be less comfortable. I save them for when everything else is in the wash. It's too bad, because they're soft and the lace & colors are cute-- they just need to be cut a little higher in front.

Bought around 22-23 weeks, no real change in the fit issue now at 28. I'm usually a L in underwear (and all my pre-pregnancy underwear still fit) but needed an XL for these.
