i was looking to get an authentic rockets jersey but im not quite sure what size to get either MT or LT. im 5'6 roughly 145lbs athletic build. any recommendations on what size i should get?
why don't you just go to a place that sells them, and try a couple sizes on? then order it from wherever you please.
If you live in Houston, go to the Rockets store and try them on. I pretty sure during the day it's open, so you don't need to actually go to a game. It's a lot of money to spend on a jersey that doesn't fit. You can go to any NBA store, as I assume they are the same size everywhere.
I could be wrong, but I don't think any brick and mortar other than an NBA store sells authentic jerseys.
Do you live in LA? The NBA Store adjacent to Staples is open during the day. They also have outlets in Carson and El Segundo http://www.staplescenter.com/guest-services/team-la Go to one and try on sizes, then order online
Even the Medium is huge, and will practically go down to your knees. You'll need to get it cut short by a tailor.
