I hope this answer don't come back to you too late!
Although a newbie in the real world myself, I would suggest searching a little bit of fashion-related projects within your agency. Try to get to know as many people as possible through the projects. You never know if one day someone has a project openning and your name might just come up! The power of networking is quite amazing!
If you want to "search" for related job openings, careerbuilder.com and monster.com usually have a well broken down categories for you to search in. They work pretty well in US.. I am not too sure where you currently live in.
I have been wanted to do consulting in fashion industry as well but I think a simple bachelor's degree just won't cut it
