I ordered a pair of Vezalli patent knee high boots in size 7 (my usual size). When they arrived they were much too big on the foot (but fine on the calf etc), so (after speaking to a member of Lotus customer service staff) I ordered a size 6. These fitted well on the foot but were way too tight of the calf and too short (About a inch shorter in the leg than the size 7!) so these were no good either. I've had to return both pairs at a total of £22 because Lotus don't enable free returns to Collect+ etc or refund the cost of postage. On the plus side, they did arrive very quickly on both occasions.
