Dorothy Perkins has a lovely printed tunic in right now which I'm loving for the coming warmer months. I'd wear this to uni with a long purple cardigan and wide leg jeans. It would also look great with white trousers and a jersey shrug come Summer. Add a lilac (or maybe cream) hijab, comfy flats and a roomy bag in a neutral shade and you're good to go:
Purple cherry print tunic £25, Dorothy Perkins; purple hijab £6.29, Muslim Base; knitted long line cardigan £32; indigo wide leg mooch jean £40, both Topshop; cream ballet pumps £15; rhinestone frame ring £7, both Dorothy Perkins; casual bag £6, Barratts.
