I ordered a 2xl. I'm 5 foot 5, weigh 170, have a 33 inch waist, and a 47 inch hip. I'm SUPER curvy and I can never find pants that fit - let alone scuba gear. These are awesome! They have a draw string waist, so I can actually make them fit my waist, and they come all the way up to my natural waistline, so not but crack showing! They are about 3 inches too long on me, but I'm gong to hem them, so it's not a big deal. I wonder if I could have used an XL . but they were out of stock.See full review
