From Trend Patterns:
Drawstrings were a big feature on the SS17 catwalks, seen in New York, London, Milan and Paris fashion weeks, and made a lot of reappearances in the AW17 shows too, as well as a sporty, label trend.
This dress is a great mixture of the two trends, as seen in our samples below, so is perfect for a casual daytime dress (made in jersey) or when made in something luxe you can morph the design to an evening look (made in Lame). When made in a patterned fabric the print will be distorted by the drawstring to make an interesting, unique look.
