I'm 5'9", 165 lbs, and a 36DD. I typically wear a 8/10 or M/L, and I ordered the L in this suit bottom. I think Inamorata is one of the only brands that actually sizes their suits well. I liked the fit of the L, but I could have also probably fit into the M. (Whereas with countless swim suit brands, I'm needing an XL minimum in bottoms.)

So I think sizing with this style kind of depends on how you like your suits to fit! I sized up and liked it -- super high cut in the leg, super high-waisted (like, actually!), and the quality is great. My only note is the back rides up with any movement. So it's kind of like a constant wedgie. If it had less fabric in the back, it'd be fine as a thong. But I think it could maybe use a touch more so it doesn't ride quite as much. Just a heads up!

I'm 5'9" and 165 lbs with an athletic frame -- thicker thighs, etc. I typically wear a M/L and a 8/10 in most pants, shorts, and underwear. I also have an incredibly difficult time finding flattering swim bottoms, so I was super stoked to have found these. I ordered a L and loved the fit -- not too tight but not too loose -- though I do think a M would have also fit. (Some L are NOT larges, but I do think this one actually is, just for any true-true L wearers out there!) They're extremely flattering -- very high waisted, went past my belly button, and hit right at my waist. The back is cheeky for sure, and the only con is they kinda go up my cheeks as I move around.

They're also extremely comfortable and great quality. I just wish there were all the OG patterns in this style -- neon green leopard, giraffe, etc., even the new '70s leopard that came out last year. Overall I highly recommend giving these a try!
