I've never been a fan of yellow. Thinking back on my wardrobe from childhood until now, I can't recall any pieces of yellow clothing. Not only did I not care for the color, I always thought yellow looked best on darker skin tones (not me -- I'm at the far end of the pale spectrum.)
But it's hard to ignore the magazines that are suddenly featuring yellow clothing like there's no tomorrow (it's the new summer trend, along with purple makeup). It felt only right to write an article about yellow children's and teen clothing -- and to my surprise, when researching (a very serious term for browsing online stores!) I found many options that I actually liked. Each of the dresses and tops that I featured in the article are pieces I genuinely like. I can't say I purchased any of them, but I did admire.
I think a big key to yellow it what you pair it with. I prefer to see it with neutrals, such as brown and gray, rather than other candy colors. And you'll notice that all the pieces I listed are simple fabrics, such as cotton. Yellow feathers, fluff or marabou is just too Big Bird!
