I'd really thought those simple designs would win as it can be used for their generic branding. I am a designer myself but didn't bother joining here. I've already seen a lot of similar styles of logos like those who've win and I personally didn't liked it. It is too obvious that they've plagiarized with the uncleanliness of their works. Also, if the client wants to have a versatile logo (just a suggestion), they better chose those that can be for their general "fashion" business. Having a womenfigure in a logo would be seemed to be a business mostly for women's fashion, henceforth onto having men figures as well. If they also wanted to be a famous brand soon, they better be looking on what are the logos of famous fashion brands nowadays, most and almost every brands do have generic logo, and they better chose those logos that were made with vectors, they might find a problem if they chose those winners that would only provide jpeg files, it'll be blurred if they scale it up.

I am just saying my personal designing critiques. I hope the OP would reconsider looking at the bigger picture. Logo defines their business. It is critical.
