Yeah, have been researching.... expensive dinner got more expensiver...+missus wants a new cocktail dress as well....
Thinking I might do black shirt, black bow tie, black cummerbund and black suit?
I use to go to a lot of black tie and trust me that you CAN tell the difference in these sort of events. Something like a wedding is easier to get away with but a ball you cant.
You cant mix and match a cummerbund (a black tie piece) with a normal shirt and most defiantly not a black one.
You should be wearing a dress shirt with a cummerbund and bow tie. A dress shirt is white, double cuffed and pleated or bibbed. You can go for either collar style but if the shirt is not pleated or double cuffed, it will look closer to a school shirt than a dress shirt.
As for the black suit, some modern styles look similar from afar but that is about it. Dinner suits have black satin, giving them a very distinctly different look which becomes increasingly obvious when surrounded by black tie. There is black satin on the lapels and along the length of each leg.The lapels are also winged OR shawl style but never notched like a business suit. The Trousers also shouldn't have belt loops and are kept up with bracers, although some more modern suits have adopted loops.
You can replace the cummerbund with a waistcoat but these are also a different cut, as they normally scoop down to show the pleats of the shirt and are the same satin material and the lapels and leg line.
I have been lucky that i have not changed in size in about a decade and currently fit all three of my dinner jackets but if i did put on a few stone tomorrow, i would most definitely look to buy a suit to keep in the back of the closet.
I i were you i would:
-Get a dinner jacket from somewhere relatively cheap like MnS or Burtons, pay an extra 20-25 to have it taken in if the fit is terribly bad off the shelf
-Buy a proper dress shirt from the same store. My opinion is to go for winged tips if you are opting for cummerbund and bow tie
-Buy a set of discrete steel arm bands if the sleeves are too long, it will look better than having tehm loose and is cheaper than getting them adjusted
-Buff up a normal pair of formal black shoes and use them
-Cheap pair of bracers will mean clip on over button but that is fine, you can get a convincing pair that feature leather style button loops with clips for like £10 on ebay. I suppose you can get away without if it stays up
Edit:
Here you go
