(Dress: H&M; Boots: Topshop; Bag: ASOS; Necklace: Thomas Sabo; Watch: Michael Kors; Ring: Tessa Metcalfe)
TL;DR: buy this dress. I'm normally not a fan of maxis because they tend to come out mostly in summer and are of the sleeveless/strappy variety which always make me feel terribly self-conscious. But this one balances proportions perfectly with the slash neck and the high waist. Plus, it has the added advantage of looking about a hundred times better on than it does on the hanger, and it costs just fifteen quid.
