Bad quality T-shirts

Be careful of bad quality T-shirts.  Be careful how you wash them.  Most of the time when we get free merchandise, we are the first to try it on without reading the washing instructions.  Have you received a T-shirt, wore it proudly and then after your first few washes, you find that the quality of the T-shirt has diminished?

What if you had paid good price for the T-shirt?  It would be heartbreaking, right?

Funny thing is I have bought some T-shirts from a country known for making imitations  and the quality of the T-shirt has left me dumbfounded.  It still maintained its quality and shape especially around the neck.  Now can someone please explain to me how this can be?
