"I ordered a large which was given as my dress size and everything fit except the vest. It was not even close to fitting right so I immediately ordered the next size up and it was great except again the vest was too small. I didn't have time to send it back or look for another costume so I had to sew on a middle section to make it work and I attatched velcro to one side of it so I wouldn't have to keep undoing the tie to get the vest on and off."
