I want to preorder the blahnik campari's from NM's site, but I'm not sure what size I should get. I only have one pair of blahniks-the tuccio 70 black pump. I have the tuccio in a 37.5 and it fits well with a front toe insert, which pushes my foot back. Should I get a 37 or a 37.5 for the campari? I don't want it to be too loose, but I also don't want it to squish my toes. TIA for the help!
