i hardly ever spend any time at the changerooms, it depends on whether or not an individual needs help down there though, but where i am now, its not like i'm stationed at the changerooms. but my last job they did that.... most won't though. so don't worry about that. i love working with clothes though, i cant recommend it enough - as long as you dont mind being assertive
if you want to work with clothes only work somewhere where you like the stock, it makes the perks that much more excellent (discount!) and also easier for you to sell the clothes cos you're actually genuine when youre encouraging people to buy it
