Fashion month has come to an end, and thanks to four weeks of constant street style pictures, certain pieces have emerged as the key cult buys of the season. Just in time for payday, we're bringing you 23 pieces that are about to go viral on Instagram this autumn. First, there's Chloé's new It bag, the Tess. Then we have a Self-Portrait dress that's perfect for the Christmas season. Also, there's a pair of knee-high boots that won't be in stock for long. MyTheresa is one of our favourite places to discover those new brands that have found their feet on Instagram, so you know you've come to the right place. Danse Lente, Alighieri, Staud, Ganni and Nanushka are just some of our favourites currently available from the e-tailer.
