Lucretia Winchester is famous for being in the public eye and having money. She is considered a socialite by all public standards and therefor puts up a forward front of being just that. She shops, she has active social media accounts (of which she is in charge of none and they are managed by an assistant to keep up appearances) with followers who are clout chasing.
Attending openings of galleries, movies, and otherwise means that she is often seen wearing fancy couture and pictured on non-event days dressing chic casual, though she implored her assistant to include some more 'cadid' shots of her being 'normal' to help make her seem more humble.
Though not visible to the human eye, all of Lucretia's outfits — even the couture — are generally fitted with razor-thin garrote wire in an alloy that rarely gets caught by metal detectors (to date) and, if able, knives on her person in at least a few spots. Often these are masked in the heels of her shoes or carefully hidden in a belt or sash around her waist. Guns are never on her person but she has several caches across the city in case of an emergency.
Her bag (whatever it may be: purse, messenger, weekend) has make up, tissues, a vial of perfume, band-aids, a sewing kit, her phone, a handful of mints in two different containers, and her keys attached to a keychain she got on her honeymoon. Most of those things are not what they seem but you never know.
Her personal style is generally far more casual and if she's at home she's wearing something entirely breathable and comfortable (if anything at all). On jobs she dresses in muted colors, not trying to stand out but definitely not wanting to seem like she's trying to blend in, unless it starts at an event in which she needs to be who she is to off-set what's happening.
