Navy colthing collections

The target audience for this project are 16-30 year old's who are interested in alternative music, film, culture, fashion...etc These sorts of people are unlikely to go out specifically to buy a post card, but they do visit shops.
When researching into which sorts of shops they visit i immediately thought of clothing shops. ie topshop, urban outfitters, jack wills, typical shops young adults visit. These places don't just sell clothes, but a range of products to accessorize and style the customers image.
Most places sell a 'navy/sailor' clothing collection. So perhaps this could provide a new specific context for my illustrations. In store image campaign used to promote the navy clothing collection. Products include postcards/flyers, bag prints, clothing tags/ labels, stickers, posters... Also perhaps develop into digital for stores online.
