Hi Take2020 and welcome. The more the merrier....
Flo, I do have Hiut Girlfriends, and yes they are a fairly narrow fit, but not skinny-skinny. There was a newsletter a few weeks back when they explained the style/fits' roots were based on styles that suited the original pattern cutter's body and a promise that they would offer more diverse cuts in time.
The sizing takes a try on; the first pair I got were a guess and I matched the same waist/length as some ancient 501s. These were huge, so I returned for 27/30 which are fine, and feel reasonably roomy an hour after putting them on when they've been washed. They have not shrunk even slightly and I have had them almost two years now. Unlike Elle I didn't mind the unwashed denim but I wore them for a long time before first wash so they got a bit beaten up.
Hiut also make a fairly regular 1950s style called Coda and are trying out several new designs. I have liked two of the new styles so far, but haven't ordered (only 100 pairs of each, so you had to be quick). I am hoping they will eventually follow what they have done with their men's styles and do some nice short runs/selvedge styles, plus the option to choose black or denim in all styles. It's worth signing up for the newsletter, I think as it's usually quite varied/not all about jeans, and then you see all the new styles. Presume that whatever sells well will be added to the core range.
Sorry for the essay... hope it helps.
