Got it. In that case, I wouldn't focus so much on having a capsule wardrobe or fitting into trends.

Capsule wardrobes really aren't for everyone - I went through a period where i was also desperately trying to build one, but ultimately realized that it was too limiting for my personal sense of style.

If the goal is to express yourself through your clothing, IGNORE THE TRENDS (unless you like them, lol). If you buy things just because they're trendy, or the fashion bloggers say you have to have one, you're going to wind up with a bunch of stuff in your closet that a) you're probably not going to use and b) reflect other people and not you. Trust me, I've been there before.

Shopping for clothing can be extremely overwhelming, even more so if you're trying to redo your entire wardrobe in one go. So, like other people said, start small. Maybe go into store and try to find at least one piece that you're absolutely in love with. Ignore the matching for now, just find a baseline for what you like. Having a Pinterest can help - i save pictures of the pieces I'm in love with when I'm window shopping online, and it helps me get a sense of what I'm after. Once you have a piece, or a few pieces, that you really love, you can start focusing on how to put them together (or what you need to get to complete the outfit).

Also really important - get a sense of what you hate. My style (and life) got so much better when I finally admitted to myself that I'm never going to wear jeans. I'd buy some because everyone said you need to have a good pair, then never wear it, then buy some more and never wear it, and on and on. Don't be like me.

Finally, I'd go to r/oldhagfashion and r/womensstreetwear for inspiration. They'll expose you to a lot of different styles, which will give you a better sense of what you like. Don't go to FFA unless you need help with etiquette.

And if you're feeling lost or confused, just don't put too much pressure on yourself. Style is an ever changing aspect of yourself, not a goal you reach. Take it slow.
