If I was just randomly browsing for nice clothes, I'd be able to find loads of stuff I liked... But usually when I am shopping for the DC, I need something very specific to replace something that's been grown out of or is full of holes - a hooded top, a multipack of tights, a waterproof jacket, a new pair of wellies - and I often find I struggle to find something.
Actually, I know what you mean there. There are certain items, like wellies and coats, that I've had to buy lately that have been harder to find in more unisex/neutral colours. Ski jackets were generally blue or pink, wellies were either dinosaurs or pink bunnies.
Now I'd happily put DD in green dinosaur wellies (and she currently has a blue tractor coat) but she is starting to get her own tastes and is erring towards traditionally feminine colours. So when we were in the shop for wellies the other day and she saw green and pink ones, she went for pink and said that the green ones were for boys even though she was wearing her boys coat at the time!.
I think it was the contrast of the only two available colours, ones that she is defining as "girls" and "boys" (which is fascinating in itself because I suspect she is picking that up more from her friends and from telly than she is from home, where most things we buy her are bright primary colours as I like them) that made her go for the "girls" colour. But if there had been five styles of wellies, red, blue, green, yellow, pink, she might have chosen a different colour.
So for me its not simply a matter of "pink for girls, blue for boys" that can be seen as a problem in clothing, more than there is often such a marked difference in styles, colours and logos and very little neutral, unisex clothing.
