Trying to look smart

I'm interviewing at work tomorrow and am attempting to pick out something smart(ish) resulting in a big fat fail.

I've tried on this lot and have come to the conclusion that:

a) I don't do work-smart

b) I'm decidedly uncomfortable in anything work-smart

c) I look like I'm going on a night on the town rather than a Friday in the office in my version of work-smart

Soooooooo I've mixed a, b & c and look a little like I've fallen out of a jumble-sale right now, but gonna go with it and channel Helena Bonham-Carter!
