The trends for summer 2013 are lovely and feminine. You have florals, stripes, coloured lace, pastels, brights, neon. Just make sure you don't wear all these trends on the same outfit. As you are from Amsterdam, the summer is not that long, so try not to buy too many clothes that you will not have time to wear. One or two items of each is enough. For instance, one floral dress that you can wear with a pastel cardigan, two striped tops that you can wear every year as they are classics, a coloured lace top that you can wear with jeans or skirts, a neon scarf and a pair of cigarette trousers in a bright colour. Have fun!
