Building a closet

I really want to be a more fashionable person but in my experience as a plus sized lower middle class working woman I struggle so much. Most things I like don’t have my size, most things my size I don’t like, most things I like and are my size are not comfortable for work. I really don’t like shopping online, but I do it sometimes. Not everything I own needs to be work clothes but of course I want cute clothes for work too. (I’m a home health aid and I can dress casually) any little tips or tricks or ways to help my mindset to be a better shopper? The part where most things I like doesn’t fit me makes me want to give up immediately. And I can’t just pick out a whole outfit and buy it I can afford an item or two once a month or so. So it’s hard to know when something would be a good piece for my closet. I lean in the direction of grunge but I also like colorful clothes and sparkly things so it’s just hard to know if anything I’m even looking at is worth it aka: something I’d actually wear.
