It takes a special kind of dumb to wear the men's dumb blue suit costume (no, even dumber than that). Inspired by the iconic 90's hit comedy, this outfit is bound to make an impact at any posh, high-society party (especially if you've got a friend wearing the dumb orange suit). The men's dumb blue suit is perfect for 90's parties and includes: a big dumb blue suit (duh), blue shirt, blue bowtie and blue hat.
