I use Woothemes and Templatic. Both great.
I'd agree on WooThemes - we're in the process of moving our site from a custom-build and hard-to-manage mini-CMS to Wordpress and one of WooTheme's themes and have been pretty happy with it. Their code is clean and well documented, easy to customize to fit our needs, and looks great out of the box.
I suggest to either go ahead with WooThemes or get a custom professional wordpress template for your fashion business.
If I were you I will contact a company and get unique custom designed wordpress template for my business.
