Well uhm, I'm 5'3something" and I weigh 201-3 lbs. I wear a US size 16 in jeans with a normal amount of stretch. My legs could easily fit in a size or two smaller but hey, that's what skinny jeans were made for. I definitely carried most of my weight in my stomach, but i'm starting to flatten out and fall in proportion. I figure once I hit 190, I'll be able to get into a 14 and thus, shop in normal people stores.
My top half though, fits into L (for a tighter fit), XL for a normal fit, and sometimes a size larger for more structured tops 'cause my boobs be big.
