1x is bigger then an XL. I just crossed the line myself. Depends on where you shop I guess. I just got a t shirt at goardmans that is a 2X and snug from their junior dept and also an xl they fit the same.he 1X is a little bigger, just like a 16W is bigger than a 16 misses. I am just passing through that same size area, although I am pretty much into regular sizes now. Try the regular sizes, some of them will fit you. I just bought a dress for a wedding in a misses 16-I was thrilled! -Wanda.
