We live outside UK in a hot country, but the shops here are full of exactly the same winter stock you have back home. Not terribly useful, and very limited as we don't have many shops.
My 5yo needs some stretchy, sports type shorts for tennis, gymnastics, PE, everything really. We were down to 2 pairs and now she's gone and lost one!
If I order quickly my friend can bring them out for me. Everywhere is full of winter stock. Where will I find some?
I usually get a Next or Gymboree multipack of various colours - that sort of thing.
