I am 1,8m [is that 5,11? 6ft? i don’t know💦], small top, small waist wit voluptuous hips. I usually buy L for my bottoms if it’s stretchy material, but since whenever I buy any thing that this particular model is wearing, it runs too short or too tight, I bought XL even though it is a stretchy material. The material is so stretchy that I could’ve very well bought L or even size-down to M [since my top is M]. My hubby loves the “sexy-back”. It makes ur derrière looks round, plump and bouncy too 😄 Maybe I will get smaller size if it goes on further sales 😂 Hipefully it won’t be too short. With XL it’s on the long sidr [even with me - came to mid-calf area].
