Need help finding T-shirts, long sleeves, button downs, etc.

I'm 6 feet tall - 175 lbs - slim-muscular/athletic build.

I like slim/athletic fit T-shirts, long sleeves, button downs, etc. but always have difficulties finding some that fit just right. Large usually isn't long enough and X-large is usually way too wide.

One tshirt brand that fits me very well is ZooYork, but I don't like wearing the brand even though the shirts fit me very well.

Anybody here with a similar build like mine know of any brands that I should check out?
