formal clothes recommendations/tailored suits?

Hey everyone, have you ever changed up your closet from regular street wear?

I've been in the process of changing my wardrobe, buying a couple of performance button down shirts & levis that fit my waist. I've normally worn regular tops like Nike or collar shirts & a couple other name brands, but now I'm looking to switch my closet up to a more formal look, without screaming "I'm using this to look more professional". I wont be working at an office but will be meeting clients occasionally so the button up with dress pants or jeans would be optimal. But I also need at least one good tailored suit for any situation that might pop up…

Any recommendations on performance button down shirt brands/pants brands other then Levis? My knowledge is limited when it comes to brands. Hell those performance shirts I bought are all the same one brand.

And, Do you know of any tailor around Houston/East Houston that you recommend? I've found two near me that sound good on Google reviews, but I decided to take a shot if any local knew of a good spot… thanks!
