Fashion help.

Hi.

I don't really know where else to put this. I'm kind of new to this game. Basically what I'm trying to do is to imitate puu.sh/jT0Gd/1ef398815d.png . I don't know much about costumes yet so I'd like some pointers. Thanks.

First of all, we have The Fashion Thread where you can post pics and ask for ideas.
Then, we have some resources:
Cirnopedia: Recolorable Outfits. Set Color Outfits. Accessories. Hairstyles.
JP swiki: Female Costumes (Google translated)
bumped blog: Scratch Catalog

As for your desired look, while not exact, I would hazard to say that Cathedral Cross (カテドラルクロース) or one of its variants might be the best fit, with the default Toque Hat (トーク帽), a Short Cloak (ショートマント), and a Book Strap (ブックストラップ).
