I'd personally say avoid LCF with a stick. My friend was on the fashion merch management course and she says it's a joke. Full of unsuccessful art students and people who don't speak a word of english. When it came to group projects (which is nearly every single one) she was the only one doing any work, and they apparently twisted it so it looked like they'd done it all
I don't know how people find the merch management course at my uni (westminster), but i've heard good things from the PR departments. Whereas I'm in the fashion department and we have excellent links. However you have to remember that most fashion management courses will come under buisiness school umbrellas, not fashion. I suppose you could get in with people in the fashion department though which wouldn't hurt?
Ravensbourne, which is moving next to the O2 in 2010 has a brilliant promotion course, however you have to get onto the course as a fashion design student and do all the pathways to get through
UCCA epsom is doing well on fashion design at the moment. However you would probably have to rely on the links from the fashion design course
University of Manchester is a well respected university and you would hope you have good tutors from that. Though I've heard bad things about fashion design courses at the big universities.
Nottingham Trent is brilliant for textiles and has the actual student life.
The advantage of being in London is the obvious industry links
Do not let people trick you into picking LCF because it has the word "fashion" in the name. They've lived on that reputation for too long and are scamming students for stupid amounts of money (my friend in final year fashion design had 5 minutes contact time a week and there was no promotion of students apart from a room full of everyones buisiness cards). If you want to go there that's great but research all universities good and bad sides
