i hc that amongst a thousand other things essek's wardrobe changes after the nein, & it's mostly because jester loves clothes and shows love through them too so whenever she gives essek an accessory or clothing item that reminded her of him essek has absolute no other choice than wear it as much as possible.
it's starts with the parasol, then gardening gloves, which were both made with essek around so they're the most discrete as much as ruffles and lace like patters can be discreet, but then in her journeys she's starts to find eccentric jewelry and wildly out of fashion, out of age, camisoles and embroidered pants and she keeps most of them because they're funky and she loves them but then there's the ones that are dark and/or purple and have geometric shapes in silver, with spikes or in soft velvets, maybe sometimes even with amber thrown in there, and what is she even supposed to do then! like she has to now! he'd totallyyy love them!!
and essek. essek always tries them on the minute she hands them to him, and he always does a little pose, sometimes even stays stills as jester draws him and it makes his heart grow in size and warmth and he's always, always thrown for a loop, gets stuck on it for a while, because he doesn't think it'd ever fully click, or he'd fully understand or much less believe that she loves him this much and he loves her just as much and then some.
he thinks that to be loved by jester lavorre is a gift and a blessing that should be treasured like the most precious of gems, even if she gives it out freely or maybe because she does, so he keeps it close to his chest and loves back with everything he has, even if (or maybe because) it means he has to wear bat shaped sunglasses and pattern on pattern suits.
