I find Boden sale very useful for boys' clothes in fun colours.
I also put my daughter in every colour other than pink, from a variety of sources, till she was old enough to insist on "da pinky one".
She also refused to wear a number of items in colours she thought were not bright or girly enough, so it was easier to go for what she liked.
My son would have been very happy with pink sparkly shoes as a young preschooler but we (esp my husband) felt it was not going to be helpful in the medium to long term to choose accessories which might cause comment and/or teasing and encouraged other cheerful colours such as red for sandals.
At 8 he is very keen to look a) masculine and b) cool. I note that, for example, big hibiscus style flowers on surf shorts are very surfer dude, but he isn't at all keen on this. I note also that pink items for young boys/ men can be the height of cool on the right person, but often these languish in the sales.
I am very happy for them both to choose their own styles within budget and reason now they are at school, but they are both opting to conform with gender norms pretty much.
