please dress me! Interview

[arrrghhhhwaiting]

Got some pgce interviews coming up... What should I wear?
I'm a size 12, short ish.
I want smart but preppy/don't want to look like I'm going to a funeral. I don't really own a suitable jacket, so need a jacket too!

Budget? Which shops can you get to?

Something like this would be a decent length on you (not like the Amazonian model)- would look good with opaques, shoe boots and a jacket.

Warehouse had some great suits I got a nice grey check one (they do skirt and trouser versions) Came to approx £100

Will link tomorrow
