The daily theme varies, but it's still mainly about beauty and lifestyle. Besides posting your own pictures, you can 'like' others or just scroll down to get inspired. You even get the chance to win something, like a giftcard, if your picture gets popular.
Although I just found out about this website, I'm already enjoying it quite a lot. So if you're having some spare time I suggest you would just go to aboutmystyle.com, it can be really enjoyable to watch other people's perspectives on the themes. And as the header of the website says:
Fashion fades, only style remains the same.
