What you are considering is a trend that has already begun. There are numerous of websites where one can trade and/or give away personal items with/to others online. One particular name for a reputable website does not come to mind; however, there is Rehashclothes.com, Dig N Swap, Bigwardrobe.com, Swapstyle, thredUP, and Close Infinite among many others. Check them out thoroughly before you start your trading. Hope this helps...
