The new subreddit 'Pretty Girls Ugly Faces' does what it says on the tin.

It's a place for female Redditors to upload pictures of themselves looking pretty - ie. as they normally look - and, conversely, as ugly as possible.

This usually involves - as any woman knows - taking the picture from below, pulling your head back to create a double chin, and sticking your teeth out/popping your eyes in the most horrific way you can. Such as here, for example:

Depending on how you look at it, the results are either a brave and thought-provoking experiment in female beauty and the male gaze, or just really silly and very funny. Here's just a sample for you, below - check out more on Reddit...
