Im glad I read the reviews. Im a size 10, 54 tall, 150 lb & muscular build (I do CrossFit). This is a size XL bikini bottom & it fit perfectly. When you first try it on, you might think, oh this is more modest than I thought, but once you move around, it adjusts & yes, it is cheeky. I saw some reviews complaining that it doesnt have full coverage in the back. Thats the point & its literally in the title of the product. Just be prepared. It still covers way more than a thong. It has a boy-short fit in the front & the front doesnt ride up or move. The entire bikini bottom is lined with black fabric so there is 0% chance of show-through. Im short-waisted & this came up over my belly button. Id have liked some ruching or slimming panel in the front because usually if a woman is looking for a high waisted bikini bottom, she wants to camouflage the tummy. This covers the tummy ok, but if it had a slimming panel, Id be happier. The bikini top in the pic is also from Amazon; search Fantasie brand & it comes the same size as your bra.
