If you took people's advice every time they said 'if you buy one thing this season, make it a...' you'd probably have a wardrobe to rival Cher's in Clueless. Every season there are dozens of 'key' looks to choose from, and someone somewhere always tells us theirs is the one to buy into. Of course designers do it deliberately to create demand and force us to cough up the readies for yet more stuff we don't really need.

That said, this season you'll probably find you do need a pussy bow cut-out blouse or tee like this one from Miss Selfridge for £22. Why? Because it's pretty! What better reason does a girl need? It's this week's bargain pick of the week for ease of wear and up to the minute style.
