Three years ago, at my own wedding, I was appalled at what some people wore. One woman showed up in a skin-tight, crotch-high minidress; another showed up in a ratty dress from the early 90s (it was faded; she looked pretty horrid, like she just rolled out of bed); and another wore thigh-high come-fuck-me boots.
People, you're at a wedding. Decorum is called for. Our wedding was no princess wedding. It was held at a reception hall, and yet a select few felt it okay to look like they were trolling for sex at 2 a.m. on a Saturday night.
No matter how "casual" the wedding, please show your respect when you dress. Your clothes are one way -- a very loud way, if you will -- you communicate your respect - or lack of it - for the people and places you encounter.
Yahoo has a pretty interesting article on 9 Things You Should Never Wear to a Wedding. Many comment-posters made some stupid comments: "These are basic things that people know." "These are obvious; people already know this." Uh, no, folks, unfortunately, they don't.
What killed me about my guests was they knew better: I've attended weddings with all 3 of these offenders, where they dressed well. Why did they dress like shit for my wedding? My guess is they don't respect the Bitch.
