Went to Lulu yesterday and tried on a pair of fast and free high rise split 3in”. I’m a size 0 in aligns/Wunder trains, and a 2 in the align shorts.

I’m 5’1, around 87lbs.

Tried both the XXXS and the XXS. The XXXS felt like the seams were gonna pop when I pulled them over my hips and when they were on, it felt snug. The XXS went on with ease and no trouble. Since it has a drawstring should I go for the XXS?
