The fit on these is really small even compared to the yoga waist full leggings from Leggings Depot. They are borderline tight and I normally wear about 8-10 in pants. Not sure if it was just this pair or if all the cropped leggings from LD are like this. The quality also was pretty junky with a lot of threads hanging out. Just don't seem to be as nice as the full lengthy yoga leggings they make. I've found a different  brand that is much more roomy in the OS. Basically unless you're pretty slender I would not recommend the OS size of these.
