i want to buy or rent a breakaway tuxedo, but where can i get one?

Have you checked with local costume-rental shops (the kind of shop
that rents Halloween costumes and such)?

Another type of store you might want to check is local "Adult" shops,
specifically the largest one you can find. I am assuming this is for
quick removal in front of an audience... ;-)  Many exotic dancers find
their costumes in stores like this. If they don't have one, surely
they will know where to obtain (or rent) one.

Howdy bigron!

Easy enough to make one for yourself, and probably cheaper.

Buy a used tuxedo, one or two sizes large, get some Velcro from
your local Home Depot, etc. and then cut down the center of the
back of the jacket, shirt, the seat of the pants and the inseam
of the legs.  Stitch the Velcro on both sides of the cut areas,
underneath so it won't be seen, then overlap (the reason you got
an oversized tux to begin with) the Velcro areas.  One (real good)
tug and it comes off.

Looking Forward, denco-ga
