I think GHD hair straighteners are the best. They are expensive, but well worth the money and last forever. I got a travel hairdryer and small straightener in a set.
If you want to check out some styles of clothing here, just have a look around at some UK online sites and see what types of clothes they have available:
Next, ASOS, Dorothy Perkins, Boohoo, River Island, New Look, etc. are all lower to middle price range. Some popular brands I see a lot are Firetrap, Replay and Super Dry.
My DH mainly complained that my jeans were too baggy, as sb15 says, I think people here tend to wear tighter-fitting clothes in general.
