Piscine Blue Jesse Kamm Sailor pants

Size M Jesse Kamms. Equivalent to a size 6. Bought off need supply (R.I.P.) on their website a few years ago where it was labeled a 6 on their website but these ones I received are just labeled a Medium. Her newer colors are labeled numerically, I believe, and piscine blue is one of her older colors with XS, S, M, L etc. sizing. I gained weight over the pandemic, wore these once and my tummy busted the top button off but I re-sewed it on.
