Volume was created and constrained all over the catwalks with the use of the good old drawstring. Giving clothes both a sporty and utility feel, drawstrings were seen everywhere. Sportmax used them in more traditional ways in lightweight jackets and then more experimentally to create little circle details. Marni used them combined with plisse pleated fabric to give even more volume to their shapes. Versace used them with shiny sporty fabrics, whereas at Loewe softer natural fabrics were used, and Louis Vuitton used elastic to gather in silk jersey.
We've included some images of great gathers as well which could've easily been drawstrings too.
