I have found a basic one so far: Glamstorm
It is sort of part doll dress up, but it does have some options from actual fashion brands. I'm still trying things out but in the spoiler is an example of what the fashion creations look like. It looks like there is only female fashion for this site.
If anyone finds anything else it would be appreciated. It looks like a lot of the sites are taking down their fashion creators from what I've seen in my search so far.
