This made me smile the instant I saw it! Adorable :-) I agree about the difficulties of wearing yellow too but you've done a great job of incorporating it here (in my humble opinion)...
I think it's because yellow is such a hard color for most people to wear. I love it but it makes me look unbelievably sallow unless it is not near my face or is *exactly* the right yellow so I tend to add pops of yellow where I can (mostly in my sets rather than in real life). I wish more shades of yellow were available to buy - when it is available it is usually in bright or mustardy shades that are really hard to impossible for most people (ok, me!) to wear. I do love yellow, though. I painted our kitchen an awesome yellow & it is my favorite room in the house!
