I'm 5'10" and 145lbs, bought a 4T. The quality is just ok, the interfacing immediately wrinkles on washing in a way that is impossible to fully iron out. Ive had issues with this with Jcrews other dress shirts. The other problem is the the sleeves aren't long enough and the shoulders aren't wide enough to be considered a tall. There are other brands out there with comparable prices and better quality dress shirts. Its also huge in the waist.

I have purchased 3 of these shirts for work and I absolutely love them. There aren’t many stores that offer tall sizes in tops, which is very frustrating for someone who is 5’10” with long arms. Will definitely be purchasing more.

I have a few slim-fit shirts from a few years ago and they are my best-fitting button downs. I took advantage of the sale to stock more colors/patterns and I'm quite disappointed that it's not the same shirt. The fabric is thinner, and the fit is tight in the chest (and I do size up for button downs despite being fairly average-busted) and huge in the waist compared to the more feminine fit of the older shirts. It's still a decent shirt but not as flattering and overpriced for the quality. Also, I wish they offered more colors in tall, it's always white, black, or blue. I remember when Jcrew had fun fabrics done in tall sizes.
