Something I've been meaning to start a thread on is the gender difference in the construction of children's clothes.
Girls shoes that are slippery and more difficult to run and climb in, which presumably can inhibit physical development. lacy cardigans with sequins on them. I know. Don't buy them, but why do I have to go to the boys' section to get a decent hoodie or unslippery shoes, or, as in Next, plimsolls for PE? "sorry we only sell plimsolls for boys" WTF?!?!?
