Re: Fancy Dress?
Yeah it's a general pain in the ass, but really no one is FORCING you to do it. It's just that you'll stand out like a sore thumb and probably receive negative criticism from others if you don't dress up.
I hate dressing up but I did for my sister's wedding because it was a major occasion with photos and everything and if I dressed like a normally do (goth/punk/metal), I know I'd NEVER hear the end of it. I decided one day of dress beats a lifetime of hearing about how I was a jerk for not doing it.
Now if it's not something major like say a siblings wedding then I say just dress however the fuck you want but depending on the event YMMV.
You've gotta want it!
