TK Maxx can be very hit and miss, but sometimes you'll find some absolutely awesome shit.
Went in there recently for a shirt, came out with a nice shirt and the best fitting pair of jeans I've ever bought and cost like £30 in total.
For £100 if you scour the rails you'll be able to come out with a couple of pairs of jeans, a shirt, a couple of t-shirts, and probably still have a bit of change.

This. Those white Supreme t-shirts run you at least half of OP's budget.
