I think it’s totally personal. Maybe you are ace, but even if you're not, this is not determined by what clothing you find attractive. I tend to like androgynous people and I love alternative styles. So if I don't like the way someone is dressed, does that mean I'm ace? No, it just means I don't like this certain type of clothing. (not to say you're not ace, I don't know. But this is a theory on people who are not ace but just don't like the clothing others like)
By the way, I've also been questioning whether I'm ace, but I just don't really care, I do what feels right and doesn't harm people. This is the most important thing: being happy, regardless of the category you find yourself in.
