Thank you so much everyone!
Tethersend - some of those dresses are perfect, thank you! I really like the long sleeve one, but I think you might have to be very willowy to pull it off.
I'm 27, a curvy 12 (still losing pregnancy weight) and 5'8. Still breastfeeding and have a huge bust at the moment. I'm applying for secondary. Also, it's for a School Direct place, not a college place, so I think I need to be a bit smarter than if it was for a PGCE.
So cardigan out and jacket in.
Rebecca - I don't wear trousers just because I feel really uncomfortable in them. I think it's to do with sporty thighs and insecurity.
Willowstar - that's the kind of thing I would normally wear, I think it sounds great.
