guys
I am starting a brand and I want it to be in the higher price range and of very very good quality. I ll deifne this for you before you ask me

a heavy t shirt, very thick, that fits perfectly (not huge like we see a lot now) and that you can keep for ever because it does not "move" or "change" once you wash it. I have for instance a jordan brand t shrit i bought maybe 15 years ago and it is very thick, never move and i thin the best quality shirt i ever had.
knowing that could you help me understand what brand i should go with. I must also add that I would like no tags on the shirts so i can put my own (that you guys will help me find later....)
in your opinion what brand and prices should be
poor quality:
good and great to start your business with
very goo to exceptional quality (as define above):
I will not buy juts white (in fact almost none) but one color shirt and maybe some with neck and last part of the sleeve of a different color (not sure how you call that)
thanks for all the help
tom
