Danish brand Ganni has become something of cult favourite over the past few years in part thanks to its instantly recognisable seersucker midi dress that fashion editors and Instagram influencers haven’t been able to get enough of. High street stores such as  Next and H&M  have even created their own iterations of the design and now it seems it is Mango that has taken inspiration from Ganni with its check baby doll neck dress that had us doing a double take.
