I received my XXXXL yesterday in the mail and I have to say it is so darn cute and made really well for its price! I ordered based on my measurements and it was still too small. I am 5'7 and 240 lbs- I normally wear an XL/14-16 in pants but I have to wear 2x in tops because of my mid section. I could only fasten the corset on the last hook and after that I gave up. I am going to keep it but I will have to order a 6X in order to have this fit. Im still pretty excited about it though! That will be 4 sizes bigger than what I usually buy in US sizes.
