the position i'm in right now suits your question very well...
i am in my final year of high school, and thus far i've taken fashion for the last to years...what i learned were basic sewing skills (how to make a tote bag, pajama pants, hooded sweater, darts, pleats, gathers, hems, etc..) this is very very helpful and crucial if you'd like to pursue fashion in post secondary education...friends and profs from university stress this very much,
those who do not know how to sew are going to either flunk out or get kicked out...i pursue more complex projects on my own: beading and more complicated patterns...
>other helpful things to know are about manufacturing and production. what is CAD, what's grading, types of weaves, etc., etc.
your illustration skills should be mature, know the difference between natural (8 heads) and 'illustration' (10 heads) proprtions..my fashion course taught me
nothing about this, in this aspect i'm self taught...
- really helps if you're knowledgeable in visual arts...

the reason i'm telling you this is because right now i'm in the process of completing my portfolio (two actually, one for a fashion design program, one for a fashion business/marketing program), these ask for things like 4 illustrations, 3 garments, two graphic pieces, 1 self-portrait, blah, blah, blah..
everything i've learned about fashion and art both at school and tfs
blush
i found so extremely helpful...
ABOVE ALL though...if i was not as passionate about fashion as i am, i would be doing everything half-heartedly, and i definitely wouldn't take 20 mins to read an article about hedi slimane, or learn about why satin is shiny just because...make sure you find yourself caring about fashion, otherwise (imo) it's not worth pursuing it....
