When it's so pretty you snap it up without paying attention only to later discover you should have thought better. That was the experience of a certain Shannon Brown, who is thought to be from Scotland. She discovered her newly purchased PJ set from Ann Summers featured antique illustrations of multiple people having sex.

Shannon posted the image of herself wearing the pyjamas to Twitter (left) with the caption: 'When u buy ur Pj's out of Ann summers thinking its a cute design, to go home and realise folk are shaggin all over u.'

The £21 nightwear is aptly named 'The Voyeur Lace Set'
In an online description, the retailer hints at the nightwear's risque designs.

'The Voyeur Lace Set is a delightful concoction of comfort and sexy rolled into one. The cami has soft sheer lace cups finished with a big bow. 
'The subtle monochrome print, reminiscent of French romantic illustration, looks innocent but upon closer inspection...it’s naughtier than you think.
