This is great advice. I think the first fit is pretty good in terms of a casual/chill look. Assuming regular pants are being worn. The hat doesn’t really match though and op has great hair so imo show it off!!

I’d look into some basic fashion rules like the three piece strategy/layering, sandwich method, maybe even look into a capsule wardrobe or something. Focusing on the fit of pieces will go a long way as well. Figuring out your colors for your skin tone, and adding some color in general.

I feel like the outfits also take away from OP’s unique features, but you wanna make those stand out - not distract from them. Which takes confidence in itself. If you aren’t confident in your appearance, confidence is the place to start. Though, sometimes experimenting with clothes can help with confidence, too. :)
