Makers 'Skin Italy' say the tan tattoos are there to give wearers a memory of their summer holiday and turn the imperfection of tan lines into an advantage.
A spokesperson for the company which sells the £35 bikini said: "During the next summer holidays, the marks left by your bikini won’t any longer be unwelcome pale stripes but a rather intended small heart.
Love the idea. Now a girl can have a heart tan on her ass thanks to this special bikini. Looks very cute.
