Birds of a feather...fall off their perch due to hypothermia

If we weren't about to take our first tentative steps into winter...and are therefore anticipating months of layers...I'd probably rush in (where angels and other winged messengers fear to tread) and buy this organza sleeved number from Topshop...but what good are organza ruffles when they're either hidden under knitwear and coats or framing a rather unsightly mass of goosebumps?
