It's one thing to upload a picture with dodgy Photoshop, but it is quite another to share an image that includes the photoshopping instructions. 

Luxury online retailer Net-A-Porter is in a bit of hot water this week after the site uploaded an image which shows a perfectly slim model showcasing a pair of designer socks.

What's unusual about this photo however, are the arrows which point to the model's legs, arms and hips which play host to the command "please, slim."

The image seems to have been uploaded accidentally with the instructions still attached, in place of the photoshopped picture.

The model, whose name is Amelia according to the picture, already looks very slim, and the luxury brand distributor has been called out online for its unnecessary retouching on a photo flogging a pair of socks. 

The image has since been removed from the website and replaced with a new edited version, but not before it was noticed by shoppers.

"@NETAPORTER you might want to edit this pic or better yet delete it??" tweeted one fashion fan. 

While we're all pretty aware that most images in the fashion industry are manipulated or altered in some way, this blatant display of editing a model who is already thin to be thinner is striking. 

Net-A-Porter has yet to comment on the issue.
