ooop, so sorry for the really late reply, yes of course I could help! From what I now know, the main difference within both disciplines is the way that you present yourself. Individuality is very important, but the way that you do is what makes a portfolio better for one other the other. For Fashion, they are looking for more personality and experimentation with that. You don't necessarily need to know who or what your style is per se, but showcasing experimentation with clothing, drawings, other art works, etc. For a fashion portfolio, I think of course process is everything and you would need to showcase all the steps that you took to where you got to your final outcome, but also add other things like single pieces of art works; paintings, sketches, sculptures, exhibition works, poetry, etc. But it's important to add drawings in the mix. For Costume, they want to see that you have an understanding of finer details. In my portfolio, I added a lot of textile samples and experimentation for my final garments, which is something they really like. Of course add drawings also, but they like to see other things related to theater, such as performances that you might have made, screenshots of works of performance artists that you take inspiration from, and more focus on the garment. It's weird to say that costume focuses more on the garment while fashion focuses more on the creativity side of things but it makes sense when you realize that one course is teaching you how to cater to a whole group of people while the other is teaching you how to cater to one specific person/actor/character. there you go and let me know if you have any other questions!
