So many!
Kookai and Morgan - I wouldn't be still shopping there now but when I was 15-21 I got some great stuff in there (cream wide leg trousers and a red asymmetric top from Kookai, black satin hipsters from Morgan).
Obviously Topshop, Oasis and Warehouse. Still have lots of things in my wardrobe from all of them. I know they are online but they aren't the same.
I missed Debenhams this Christmas, it was always good for buying Christmas presents for my Dad and husband as well as having all the concessions, the lingerie, home department. If I want to buy a new duvet for example in our big shopping centre I can only think of marks and spencer and tk maxx now that would have them. And I'm talking one of the biggest shopping centres in the UK. There's much less choice if you want to go out and buy something and then online it's just overwhelming!
