Size? is a British retailer with a focus on offering a curated selection of sneakers, apparel, and accessories from popular brands in the urban fashion and sportswear industry. The brand is known for its collaborations with well-known footwear companies and for providing a platform for exclusive releases and limited-edition items.

Together with Paper Trails Europe, Size? launched a street marketing campaign consisting of both guerrilla and Out-of-Home media. The streets of Milan were taken over by a mixture of A1 posters, in four different designs, and A4 Square Stickers making sure every part of the street lanscape could be hit. These formats together with a billboard located near Porta Ticinese made it so their campaign was heard to go unnoticed.
