Round 5: Merida's blue-green dress

Round 2: Cinderella's blue nightgown
Round 1: Mulan's blue sleepwear

Aw so sad that Merida's dress left. I absolutely adore the color (it's one of my favorite colors ever) and it looks so comfy to boot!

Ariel's dress doesn't stand out to me, although I like the bow in her hair.

I still don't see how this dress is appealing. It's confining. It's much too tight, for one. I also don't like the pearls sewn onto it, and I don't like the wimple, either.

Same reason as before. Too tight, uncomfortable, and the weird wimple.

I like the blue and gold dress

The colors are gorgeous but there's zero functionality.

It is quite tight and uncomfortable. Otherwise, it's a quite pretty dress.

it's very plain and the apron just kills it further. I thought it was about the dress and not how it looks on the princess?

I don't like Aurora's dress

Of all the dresses, Mulan's is the least iconic. The other's have very memorable scenes in their blue dresses or it was their main attire (such as Belle and Aurora).

It's a nice dress, but the wimple just ruins it.

Like I said before the wimple pretty much ruins the whole outfit.

I actually really like Merida's.

It looks tighter than Aurora's dress. The headdress is weird. The colours seem to flashy.

I don't like the color a lot.
