Thanks everyone! Leaning towards keeping both, esp since the wide legs are a bit discounted (still pricey, but under $100 usd).
When I say dressy, I don’t mean “formal” — they’re still jeans of course, and light wash at that — but rather “fancier than the usual iteration”. Everlane even calls them fancy jeans! The barrel legs I will wear to work in gardens, build sets, bike commute, all the daily stuff. The Mariners, I won’t. Higher rise, longer inseam, extra fabric, more “structured”. They would come out for certain parties, arts gatherings, and indoor teaching gigs.
I cannot imagine what I would put in the little front pockets. A single credit card, if I’m not going to sit down? My key fob (three keys and a tick remover) is too bulky. My minimalist wallet is too bulky. They’re just… weird.
Re: stretch factor and sizing on the barrel jeans… When I bought the Rosewood twill pair several years ago, I tried them in my usual size, one size up, and one size down. The size up looked basically the same but would have needed the waist taken in (saggy crotch). The size down would probably have been fine after a day’s wear, but the waist sat a little higher than is my preference with this shorter-for-me rise (wedgie factor). So I went with my usual size and they are structured at the beginning of the day, relaxed at the end, which is all good. Basically, my impression is that the waist increases and decreases while the volume of the legs stays pretty similar across several sizes. I have big legs for my size (thank genetics plus all the hike and bike days) so barrel legs look like straight legs on me, and straight legs look like skinny legs.
