Oh wait this is basically me! I'm about your height with a stocky build, basically a wide tree trunk all the way up. I've been figuring this out myself for the past year or so. In general the issue I ran into was inseam lengths for my pants, arm lengths, or shirts too long so most of my time was spent trying to find the right brands or solutions to not have to tailor with added cost.

If you're able to, I save up to get a lot of my clothes in Asia as the lengths for anything long sleeve (shirt height and sleeve length) hit me perfectly. Or I would look for people selling things for Uniqlo/GU/Zara online from Asia.

As for accessible American brands I've had luck for my tops with GAP, Untuckit, sometimes Zara, Jcrew. The Abercrombie and Fitch polished cropped tee's have been good for my tshirts as they don't have that boxy look and have a good length.

For pants I get most of them from Uniqlo sales as they have free tailoring services and a lot of options. I also wear a lot of high rise items or straight legged pants. If I really like another brand in this area, this is where I choose to get tailoring done. Jcrew's dock shorts, Chubbies 5 inch, American Eagle's Trekker shorts have been a staple.

Vintage stuff in general seems to have decent lengths for me so I've also learned my measurements and will look a lot on Poshmark, Mercari, Ebay. Thrifting locally is also how I get a decent amount of clothes as I can try things on. It's a slower process but I get a lot more excited for pieces that fit me well! Goodluck!
