I bought this at a Spirit store and was on Amazon comparing prices.  The costume runs true to size. I am a 12/14 and I bought an XLarge and it stated on the package that it would accomodate a 12/14.  Im 5'3" and 180 pounds.  The stockings that it came with fit, but they tended to roll at the top.  I went back and bought fishnets, took the bows off the stockings and sewed them onto a garter that I wore over one thigh.  I thought it was even cuter like this. Also, I am a 36DDD and had ALOT of trouble finding costumes that fit on top, this one fit Perfect! Wear with a strapless bra and you're all set!!
