It's a sarong with swim bottoms attached. I wear a size 12 and am 44" at the hips. I ordered a size LG and it was too small. An XL would have fit better. It is well made and has good construction, and the material is nice, but I didn't expect the swim bottoms to be attached. I'm unable to pair it with the matching swimsuit that I purchased from Coco Reef, so I'll be returning it. I hope that helps.
