Yo, I’m actually really glad you posted this because I LOVE the look of that coat! This may be a bit late, but I managed to find it on amazon—https://www.amazon.com/KENANCY-Womens-Asymmetric-Contrast-Skirted/dp/B07KSYS68V?th=1&psc=1
I hover between an S and an M myself, but I’m hoping that since a coat needs to be a bit larger anyway, an L won’t be too egregious. If it is, I’ll just return it... The amazon link includes a sizing chart with measurements so you can compare, too! Hope it works out!
