Yeah, when I was deciding if I wanted to cosplay as River or not, I basically checked to see if she had a simple outfit I could put together and this one was the simplest for the most part. At the time, I was going to be making a cosplay of a different character from scratch which is why I needed a simple one for River, but then I procrastinated too long on making the one from scratch and it's not even happening anyway (will wait until next year). lol.
At least I have River and another cosplay still though, and I usually only go on Friday and Saturday anyway.
