Banding means nothing in clothing quality wise. Unless you are buying smomething really high end.
Even the so called high end stuff uses relatively low quality garments. Majority is carded cotton and very few companies use combed or super cotton. Geez when i check shirts for like 180 i laugh at the poor quality t-shirt that is being used.
With t-shirts price doesn't mean quality sadly. Obviously your 29 shyte from mr price will be poor compared to the 180 stuff. They also use a low quality ink called plastisol which is crap and does not age well.
Whatever you do, stay away from ebay.. too hard to tell genuine or fake online.
