Although it calls itself a suitcase, there's little chance of you fitting anything but your smalls in this petite Woven Suitcase Bag from Topshop.
Based on the ever popular vintage train case, this little beauty has the added extra of a cross-body strap. The combination of the canvas and 'Chartreuse' faux-leather give the bag a real summertime feel and is then finished with an antiqued brass catch for extra vintage feel.
£35 from Topshop. See the website for more details.
