Bored of your bomber? No worries, it's time to get patch-happy à la blogger Lena Wirth. Retro-style patches are the perfect way to update a tired-looking classic (and they're super cheap too!). Lena's gone all-out high-school poster girl with her look, adding a (very Cher Horowitz) check mini and baseball cap, as well as a pair of cute-as-a-button ASOS ankle socks to finish off the look. If you're not down for going patch hunting (*cough* lazy) you can grab yourself a ready-made number, et voilà! Instant upgrade.
