WearAllWomens Turtle Neck Bodysuit Ladies Long Sleeve Stretch Leotard Top Sizes 8-14

Does the material stretch much? As I have XL bust size but S/M waist size, so unsure of which size to get

Silly question but do they popped up at the bottom please as that is what I’m looking for thanks.

The ones labelled 8-10 (not U.K. 8-10), are these US size 8-10?

Are the cream and white colours too see-through to wear with a bra? do you think they're ok without a bra?
