Floral wide leg jumpsuit size medium-large

NWT. Light and airy wide leg jumpsuit with stretchy ruched upper and tie straps. Black background with little flowers that are sort of an off-white/ grayish color and burgundy details. I’m a small and it’s pretty big on me. I think it would fit a medium or even large with how stretchy and loose it is. I am unfamiliar with the brand. It is from a boutique in Spain. Offers welcome! Lmk if you have any questions.
