Well I've read in many forums about guys turning their underwear inside-out to get an extra use out of it without washing. That is just gross. You should just get yourself off the couch and do some laundry or buy some more underwear. Jeeze. But that is not what this post is about. Up until recently, I had never heard of underwear that is actually meant to be reversed. Now this underwear is not intended to be worn two days in a row. Rather, this underwear is more like the reversible belt or the reversible shirt; it is meant to give you two looks for the cost of one. Now of course the difference in the two looks is limited, because it is still made out of the same fabric (you wouldn't want there to be two fabrics because that would add way to much bulk). But still, it is a very creative idea and will add more options to your underwear drawer. You can find quite a few reversible styles at Erogenos made by a brand called Key. I am particularly fond of the reversible purple (shown above) and the reversible blue (shown below). They are a little more expensive than some other alternatives, but they are nowhere near the cost of buying two pairs with so much styling. This idea definitely offers some great options for the future of underwear, but since I have not seen it from any other brands (yet) I cannot classify it as a trend.
