Grey tie ankle boots
Psssst! If you loved the grey Anette Oliveri boots that Sienna Miller wore but either a) couldn't afford them or b) missed out buying a pair when they were re-made (they're no longer on sale) then there is an alternative. Buy these £40 boots from Littlewoods, rough them up a bit (especially around the heels), untie the straps, cut them down and fasten them lower down around the ankle, and slouch down the tops a bit. Voila. Cheap Sienna-style chic.
