certified organic cotton

I just purchased some T-shirts and polo shirts for my on line store and I wander if any body prefers organic cotton over "cotton"  Is there actually any benefit in cotton being organically grown. I noticed that it's very soft on the skin almost silky. If any body knows more about it would you please tell me.Do people care about it and also does any body care if garments like merino wool sweaters,dresses and other garments are made in Australia, or do we just care about price tag.I know that if you want to get something of good cut and quality you have to pay a bit more than for imports.I actually don't like lots of "fashion trend's that are imported".We used to have Australian manufactures that had good designs,good quality fabrics and most of all a good fit.It's very hard to find a classical clothing that doesn't date,that fits well and it comes in a range of sizes up to 24.There is a few makers that make nice suits but unfortunately only up to size 16 and that's it.
