Paging @capnwes any help here, on links/studs?
I found mine at a consignment store, and before that nearly bought some from a discount site. finetuxedos.com, myowntuxedo.com, overstock.com, mytuxedo.Co.UK, are a few to try. If you have money to spend (think $500-$1000) Brooks Bros has several styles, both classic and flashy.
Yes to cumberbund. Covering one's waist makes the whole look cleaner, and more elegant.
I've tried every consignment store in my area that carries mens clothing, and none have stud sets in stock. If anyone has a line in either Northern NJ or in Manhattan, I'm all ears. I was trying to avoid the $500-1000 cost, because for that money, I know precisely what I'll get. I was hoping to keep it around $100, if not less (if that's even possible).
