Big Inflatable Boobs
Want to really embarrass your pal on the big night before his big day? Of course you do (why else would you bother with a stag party?), and the best way to do this is with StagStuff's magnificent Inflatable Boobs.
These truly are the best fake breasts you've ever seen, and they don't even require any surgery! Simply use the straps to attach the boobs to your mate's shoulders and let the good times roll - the straps are transparent, so nobody will notice* that they aren't real.
*Not a guarantee.
