You don't need us to tell you that pyjamas are thing for normal life by now, but we'll bet you want to hear about how Erdem's getting in on the lounge act. 

This sheer printed silk shirt, £560 at Browns, is how. Note how the sunshine yellow piping brightens the midnight blue background right up for daytime. 

It goes without saying that it would look great with matching trousers, and we think it would look equally lovely worn loose with a pair of jeans and a cami.
