I always wanted to do genderbend for a long time. Kill La Kill is one of the anime I like recently besides Free! and Wolf Children.
I have to agree the story is quite good.

I can't really do the senketsu version with thongs. I think pants is fine, LOL.
As for his normal uniform, I think he's fine with showing his upper body off. Because I generally see guys open their upper clothes in public, so yeah.... Male!Ryuuko is a pimp anyway >,>'
Also, I'm practising how to draw abs and muscles. But I still haven't got it.
Senketsu is a female now if you see those eyelashes

I like Ryuuko and Aikuro the most lol, Nudisto beach
