the kryptonite of outfit compilation

It looks like tonight I'm going to my boyfriend's gig in London. I hadn't planned all along to go but then for various reasons I thought I would go and then the Footloose dance I did around my kitchen while my tea was brewing confirmed that I may have some steam that needs letting off. The problem is I never know who to dress for these bloody things. The problems are multi-ranging.
1) The other band girlfriends are really skinny and fit so I will look like a body guard next to them.
2) I am taller than my boyfriend in bare feet so add heels to the equation and we are in sort of Godzilla/Serena Van Der Woodsen territory (with none of the perks of the latter).
3) Walking the line between trying to look a bit 'rock 'n' roll' without veering in to greeb one way or 'rockstar barbie' the other way is nigh on impossible.
4) It's London, a fact alone that makes dressing more stressful.

Yes I care too much but when your self esteem is hanging on a shoe string as mine is atm I can't afford to put a foot wrong. So past mistakes/choices look like this:


See what I mean? Help a sister out please.
