Parents of boys who like "girly" things, any recommendations on where to find clothes?

I have a 6 year old son who is super into Barbie and doing hair and gardening. He also loves colors like pink and purple and yellow. He gets all the barbies and hair stuff to play with and helps me in the garden, but I have trouble finding clothes he likes. I don't like to get him girls' clothes because the cuts are so weird and just look awkward on him, but finding stuff in the boys section is so difficult. He also doesn't necessarily want to LOOK like a girl, he still firmly identifies himself as a boy (there was a phase from ages 3 to 4 where he only wanted to wear dresses but he grew out of that). Any recommendations for where to find boy clothes that fit his interests?
