Tsdress
This week's bargain pick is Topshop's latest homage to the Roland Mouret galaxy dress. I know everyone has a 40s starlet dress in stock now, but Topshop's £40 one remains one of the most wearable and flattering. It's made from a slightly stretchy jersey rather than the unforgiving faux satin of many rivals, and the waist and front darts are much better for flattering a typically British figure (read: pear-shaped) than copies from other cheap retailers.  Get in there quick though, this sells out online as quickly as it does in the shops!
