Rain macs: not just for festivals. At least, so says Rihanna, spotted heading to the studio in Hollywood last night. As always with RiRi, there's a lot to look at here: the doubling up of slogans on shorts and T-shirts is lovely, the plaid shirt through belt loops (very nice, that one)… But the main point here is the choice of outerwear. Worn open, with the collar popped, and without a chance of rain Rihanna proves that the mac you've been saving for Splendour has legs in the city, too. Nice.Festivals on your mind? See why Alexa Chung is all about satin in the mud.
