I'm a parent but my son is in his first year at LCF, studying Fashion Photography. He asked his flatmates, many of whom are doing Fashion Marketing, for you. What's below is his - and their - take on getting into UAL and what you need to consider.
The fact you're doing the UAL course is very useful, as you can show you understand what they look for in terms of aptitude/ ability, etc. At UAL, the key messages are about talent and potential in relation to what they look for in applicants. If you have to submit a portfolio, this is really important to remember. They also like to see that you have tried to get some sort of experience in your chosen field or in related fields. How can you show that you're serious about fashion marketing? What are the positives and the pitfalls of this area of study/career?
They like people to be reflective and understand who they are and how their 'position' affects the way they look at/think about fashion. What are some of the issues with fashion/fashion marketing? Think privilege, access, environment, money. Show, too, who your influences are: which designers do you like and why. Also, who are you less keen on! Attend shows, exhibitions and events. There's an expectation at LCF that you will come with some experience of 'research' through looking at magazines, watching videos, going to events and exhibitions.
Also, are you a creator? If not, get creating! Post on your socials and develop your 'voice' there. You'll be asked to share your socials with other students when you get there, so make sure you're engaging with media and are commentating/influencing in your own right. Think about the climate, racism and social justice, and how to knit those issues into how you think about fashion. These are key elements that underpin LCF's approach to fashion.
I hope this helps!
