I am in the fashion business so I really wanted to comment on this.

While in the fashion world, long bodies are mostly used I feel the legs are slightly to long for these girls bodies, but that is my opinion.
Also, the shoes are very simplistic, so much so that they take away from the outfits themselves. Limiting all the girls to the same shoe can be a terrible mistake, because it seems as if you took less care for that part of the outfit.

Originality is also key, (going from left to right) 3,4,5,6,11,12,13 are by far the most unique. The two girls in the yellow coats almost repeat each other to closely. Being careful to make sure that each outfit is different is very important. But it is common for people to draw one piece of clothing and show how many different ways in can worn.

Although, I must say these outfits are stunning, It's hard for me to look at the artistic aspect of it because in my business its all about the clothing.

I adore your style, please post more

I really like your fashion drawing style differently from what someone mentioned above, I think the long legs have nothing wrong, fashion figures tend to have up to 12 heads long sometimes and that's ok for fashion. About the collection, it's really nice and I can clearly see the inspiration source but to my opinion dresses number 4 and 5 kinda get out of the general concept of the collection, when I see nunber 4, I think about Greece or Rome, not french style like the others, even though I can see a corset, I think the Greek elements outnumber the french ones. For dress number 5 I think the military style shirt, is too "strong" for the femininity expressed on the rest of the designs but that's just my opinion.
