Look elsewhere

With the door being locked, you decide to find another way out. On the opposite side of the colorful room, there's a wall covered with pastel drapery, a soft light evident somewhere behind it all. You carefully creep across the plush carpet and behind the big chair to inspect it closer, finding a window behind all the layers of sheer silk.

It takes some digging, but you manage to push aside the curtains enough to reach the window, seeing a moonlit garden beyond. Upon further inspection, you find the window to be unlocked, and you're able to push it open easily enough, however a chill breeze comes in on the night air, reminding you of your naked lower body.

There doesn't appear to be anyone immediately outside, but you fear running into someone on your way to a washroom is a possibility. The only thing around suitable to cover you is the drapes, though getting one down would prove challenging.
