So my girlfriend's parents are having this black tie event for some people doing this charity donation thing. I only own - 1 black suit that is now too big for me (I lifted hard weights and stopped so I lost the weight) - 1 brand new dark navy pinstripe suit, 1 vent - 1 charcoal grey suit, 2 vents - white shirts, cuffs - white shirt with minor check - light blue shirt - off color white shirt - blue tie with geometric design on it - yellow tie with geometric design on it - darker gold/black tie with geo design on it - brown shoes and black shoes I don't have money to splurge on a tux and never wear one. The last time I wore a suit or anything formal was to my girlfriend's friends wedding. I don't wear one for work ever. Any thoughts? I was thinking about going out and getting a solid grey tie.
