Not always.

I got a pair of T-shirts from These Glory Days. Wore them like 20% of time last two years and they look better then some others after 2 washes (albeit changed from them after coming back to work, and use work clothes at work, so not like they were used THAT much. So it's not always the expensive stuff that's equal to the cheap stuff. And funny thing, got them on a sale because they were pretty cheap, not really because I knew that they were quality.

Though had my wife with me when shopping and she might have "felt" the material and said that it was good for that price. Her mum is a seamstress if I remember the word correctly as somebody who sews clothes.
