The lables that are popular in Poland.Tommy Hilfinger.Hugo Boss.Replay.BenettonFCUK.Morgan.
I've been to a few shopping centres and never came across Tommy Hilfinger or FCUK store...
People in Poland wear more or less the same stuff as everywhere else :-) But, comparing Poland to UK, I've noticed that Polish women generally wear more subdued colours, less flashy patterns and are better at wearing proper clothes to their sihouette. You don't get a lot of muffin tops in the summer.
As far as lumpexes are concerned, there are some shops that sell smelly rags, and there are some better ones, with nice clothes in very good condition. The latter are a perfect place for those who don't want look everyone else shopping in chain stores. The only alternative to get something original is DIY... The only problem with lumpexes is that it requires a lot of searching to get cool stuff.
