Reference pictures for cosplay!

[matilda_kun]

So, me and a few friends are going to cosplay Hetalia, and it's hard to find reference pictures.

Belarus dress. I've seen it both black and blue. Any good reference pictues for that? I can only find fanart and screenshots from the anime, which I don't really trust >.>

Also Ukraine. Are there any good pictures of her? Especially her pants.

Thanks in advance ^^

Edit: Need some for Canada too... I can't seem to find any good pics of him ^^;
