A striped shirt and striped tights or knee socks (tights are good if it is cold where you live) and then a denim jumper/dress. Our neighbor actually made a little dress .. like a pillowcase style. patched a couple of striped squares on it... it was super cute. http://www.coolmummy.co.uk/bigandlit...ss_project.jpg
something like this but imagine just a solid blue and then some colorful little patches on it
