If you're doing work experience, tuck your shirt in. You'll look horribly unprofessional otherwise I'd imagine.
Seeing as you're unsure, I'd go with some trousers or chinos, and when I say chinos I mean well fitting, slim/straight ones, not the Topman skinny/carrot type with elasticated cuffs or anything like that. Then get some decent shirts in basic colours (think white, or pink/blue pastels). Then get a tie to wear, something that is navy with red stripes will do as it will go with all those those shirts.
Then if you turn up and that's too smart, take off the tie and unbutton the top of the shirt and you'll be fine.
Oh, your trousers/chinos should ideally be navy/cream/grey. Then get some decent looking brown shoes and make sure they're clean. Could also wear black shoes with the grey and navy.
