You know what? I'm the one that needs a utility kilt, not my partner!
So I wore cargo trousers to a concert yesterday (new ones*) because I'm not taking a bag if I can avoid it. So as my bag person (partner with large pockets) wasn't with me I had to put all of my stuff onto myself. Worked nicely.
I'm so used to wearing skirts for everything and my few trousers though wide cargos feel very similar to a long skirt.
(*not my corduroy ones which are my hobbit trousers or inadvertent kim possible cosplay, because they didn't fit the vibe I planned and the pockets are a little small)
(In no particular order in my pockets: phone/wallet and leash, coins, tissues, disinfectant wipes, concert ticket, emergency asthma inhaler, ibuprofen, tampons, lip balm, mask, chocolate snacks + held my empty cup sometimes)
