I'm 5ft7 250 give or take a few pounds - im athletic build- 38D/40 D and I sized up to 2x from my regular 1x BECAUSE this is lounge wear !!! I love the comfy of nothing too tight. yes the material is thin . but I prefer THAT . I'm 53 I get hot flashes ☺🤣👏🏽 anyways it's long enough because if you size up the length is longer

it fits nice has a lot of stretch I could of gone with a small for more fitted but M still comfy and nice.
