The first time I was putting together a 'formal' outfit, I came across this advice on the STA website;

" Shirt. You should wear a white plain style collar-attached with either a button or cuff link style cuffs. Keep it simple - no pleats at all or colour trimmings. "

That suited me fine because I perfer the plain front, but finding a reasonably priced, 'plain front' wing collar shirt locally was harder in practice than I thought, but I eventually found some at a tux rental outlet (Al's Formalwear) for about $25 new, $12 ex-hire.
I later found the tall collar 'Victorian' or 'swept wing' shirt at several UK venders like the one here; http://www.macgregorandmacduff.co.uk...irt-p-398.html

I like the look of the taller swept collar over the regular wingtip, which always looks like a band collar with little triangles sewn on to me.
