Fruit Of The Loom

My cousin outside the country is entering the company T-shirt and wants to start importing plain t-shirts for the design. What type of t-shirt is good and lasts longer say, for example fruit of the loom, and a Apparell American way. Did you also know if I can find them in different colors and designs, such as necklaces and collars round?
I need detailed answer please. Thank you for your time.

Oh, I really cute one from Old Navy yup there they are cheap and high quality

In this You Tube video called wars t-shirt they designed amazing t-shirts and made a video in stop motion. They said they have designed their t-shirts http://rushtshirts.com/ you can change the colors but I do not know about the collars or necks. I hope this helps.
