Think black tie are selling of ones that have been worn previous, not sure if you want brand new though.
Same as this.... Worth buying one if you know you gonna get a few wears out of it... Make sure you get it dry cleaned after each time though, otherwise it might be mouldy when you take it out the wardrobe. Happened a mate of mine
Every year i have to go to ONE black tie event (Master Builders), bought a suit in M&S one year, put on a feeeew pounds the next and couldn't fit into the damm thing. The suits in M&S are great value, even if you get four gigs out of it. The ones in Black Tie are second hand and can be a bit smelly ;-)
did i see tesco's selling them i think it was €47 for tennis racket and about €30 for bow tie and trousers
Pick a couple of these bad boys up here http://www.dumbanddumbertuxedo.net/dumb-and-dumber-store/product/Ra-7292-10506565-cj/ 47 dollars is a bargain
Got one pretty cheap in Arnotts a couple of years back .... Might be worth asking these guys if they sell them also - they are doing a "2-4-1" offer on loads of stuff, as a promotion in their new store ! http://www.suitablecompany.com/
