Hi Selina,
I'm desperately trying to get into this right now! Stupidly I didn't go to Uni and am now a bit too old to go next year (I'll be nearly 21)! You won't have a problem once you have a degree. Every damn job I go for requires a 'graduate' or for you to have a 'Fashion Related Degree', which you will definately have. I would recommend you go in as a Buyer's Administrator, which I have just asked a question about in the Jobs and Education section actually! This is at the bottom of the food chain, but allows you to work your way up. Companies tend to want Buyer's Assistants to have a couple of year's experience in a buying environment, so this will provide you with that. It also says that shop floor experience is an advantage as you will know a bit more about the products on offer, but not essential. There are thousands of Buying jobs out there, as I get sent updates every day... only problem is I'm not qualified for any of them! I'm really jealous that you'll have it so easy, I'm really struggling!
But good luck though.
