Transformer Chic: Meet RM by Roland Mouret's Tunic-Top-Dress!

This year is shaping up to be all about the hybrid trend. We've had the marriage of jeans and leggings to form the 'jegging', the necklace-meets-scarf (AKA the 'nerf') and now, from RM by Roland Mouret, comes the 'TTD'. Is it a tunic, a top or a dress? Answer: the TTD stands for all three. And with the latest proportion-play giving us the thigh-length boot, now is the perfect time for RM's new hybrid style. Wear it as a top tucked into peg trousers, tunic-length over narrow trousers, leggings or second-skin thigh boots, or on its own as a sexy dress. Not only does this three-for-the-price-of-one concept take up less hanger space, it's also a genius recession-friendly investment for cash-strapped fashionistas. The TTD goes on sale at Net-a-porter.com tomorrow [8th July] – just watch it fly!
