Ha! It's funny, I have a bit of a poison eye for the A-line denim skirts and prefer denim pencil skirts, so we have opposite preferences there. I actually still own one denim pencil skirt that I haven't worn since last summer. I didn't feel completely fab when I wore it, but I think I need to be really careful styling it and amp up the distinctive factor of the other pieces so I don't feel so…generic, I suppose. I find skirts problematic in general, so I might be a bit hard to please in this department.
I feel like the A-line skirts (especially in certain washes, and with button fronts and high waists) can come across a bit 70s, but not in a glam way, perhaps a bit mumsy. I know that's part of the current normcore appeal, and I can understand going with the trend, but *for me* it would feel too frumptastic. Part of that is because I'm turning 50 and have a more matronly figure than most of the women who would actually look good in these cuts (my short waist and big bust don't help -- these skirts ride up my waist and the waistband ends up right under my bra strap, so definitely NOT a good look!). I also have an association with this style of skirt in this kind of fabrication being a bit on the stiff side.
However, once I separate my feelings about the A-line denim skirts from my own flattery concerns, I can see how they might appeal. For one thing, a swingy, looser fit in the hips and thighs (if the fabric is not too heavy and stiff) would be totally appealing for warm summer weather! And I think the cut can be great for showcasing and hourglass silhouette, with that defined waist and the subtle flare. I just think the styling needs to be really current to keep the look from skewing a bit conservative for my taste.
That AG skirt is pretty cute, but way too short for me to ever consider. I definitely see why you are trying the longer one in your other thread.
