Rejected it

"We are not cutting this towel! It's made from the finest Atlas fibers my father would kill me if it got destroyed"

Yang bit her lip and said a little nervously "Then I'll guess we will just have to share"

Yang and Weiss tried their hardest to wrap the towel around each other which proved to be a small challenge because of their difference in height and cup size, but they made it work. Unfortunately, the towel could completely wrap around them so they either had to stand next to each other leaving their behinds exposed or stand back to back limiting their movement. They chose the latter option.

They both got slightly jumpy when their bottoms touched each other. But they just looked at each other pretending everything was fine. Trying their hardest to hide the fact that neither of them had ever been so nervous their entire life. The limits of the towel didn't help either, It couldn't reach completely around, which not only left their sides exposed but they also had to hold on to the edge like their life depended on it.

Regardless they slowly made their way to the door with Yang taking lead. As they reached the door Yang sighed and said "Ready?"
