Snow White - Princess Vera Wang
I chose this parfume for Snow White because it consists 苹果 notes and 苹果 is a symbol of this character. It also consists 浓情巧克力 and it's another why this parfume fits Snow White so much. I think that 水果 and gourmand notes fit her the best because of her warm, sweet, nurturing personality and her culinary skills.
I think that Anna and Su from 花木兰 II( the princess in yellow) would have this parfume as their 最喜爱的 too. These three are quite similiar personality-wise.
Other parfumes that would fit Snow White - Sring 花 Creed which was originally created for Audrey Hepburn. It consists 苹果 too.

Cinderella - Diorissimo - Christian Dior

This elegant white floral parfume was created in 1950s.I strongly associate Cindy with this era and new look.

Aurora - Mademoiselle Ricci Nina Ricci

Pretty obvious choice to me. This parfume consists wild rose( let's remember Aurora's nickname!) and rose hip. It also consists wood and cedar and we know that Aurora loves forest. It's also very feminine parfume.

Ariel - Tropiques Lancome

I didn't want to give her anything sea related because she doesn't want to be a mermaid. I thinkthat her personality is best represented 由 exotic scents because she seems to 爱情 travelling and exploring new worlds. I also should be energetic to represent her energy.

Belle - Idylle Guerlain

My 最喜爱的 parfume. It's sophisticated white floral parfume that I associate with spring. I think it would represent this dreamy, spritited and elegant French lady very well.

Jasmine -Hypnotic Poison Christian Dior

It's oriental gourmand parfume. I guess many people would associate this with Snow because of the bottle 设计 but I guess it fits 茉莉, 茉莉花 more. It's very alluring parfume and it really fits Jasmine's emotional, girly, somewhat passive personality. Original Poison in purple bottle would be a good choice too.

Pocahontas - Coco Noir Chanel

This was a difficult one but I think it really fits. It has refreshing citrus notes but also wooden and spicy notea that are associated with mystery and nature. Really Poca to me.

Mulan - Reflection Woman Amouage

It's a very traditionally feminine and elegant parfume 由 Arabian fashion house. Even its 标题 just screams Mulan. It also has magnolia, the symbol of character. Like I've already said, it's very feminine and I don't think that despite being at war 花木兰 would be a 粉丝 of unisex parfumes. It's 更多 Merida, Tiana 或者 Poca IMO. I also think that 花木兰 prefers 花 that are associated with royalty and elegance over those who are associated iwth playfulness. This Arabian fashion house seems to be a 粉丝 of 花木兰 because they also created parfumes titled Honour( but I think this one would fit Ting-Ting from sequel because of her bossy personality).
Other parfumes that 花木兰 might like: Envy Gucci. It's pretty similar to Reflection Woman and its color fits her casual hanfu.

Tiana - Black Orchid Tom Ford

This elegant parfume also consists 浓情巧克力 and Tiana 爱情 cooking. Unlike Snow's, this one is less girly and 更多 fitting for iron lady type woman IMO.

Rapunzel - Forbidden Affair Anna Sui

It's a fresh berry parfume. It's feminine but is associated with 更多 active girl than Princess Vera Wang. If 你 want something 更多 classy for Punzie, I'd suggest Tresor in 爱情 Lancome.

Merida - Eau des Merveilles Hermes

I looked for parfume which consists citrus notes that represent Merida's energy and this parfume does. It also consists pepper which fits her sassy and tough attitude. It also consists wood notes( fur, oakmoss, cedar) and Merida is in 爱情 with woods. I think this parfume is perfect for Merida! I think it would help her to stay in the woods always.
