I am 47 and I've been doing this look for years -- when weather permits, and for going out (not a daytime look). The majority of my heels are all around 1-1/2- 2 inches max though.
For example:
1) With shorter pants lengths (ankle, or the dreaded cropped), adding a pointy toe heel seems to look better with my petite proportions, i.e., not so stumpifying.
2) I still like wearing my skinnies with scrunch, even if this trend has moved on, because it adds weight and balance, I guess. I like then adding a round toe heeled pump, to add even more weight.
3) I have often worn my black ponte knit skinnies, which shrunk in the wash and are now an awkward ankle length, with strappy wedges. To my eye, it looks totally cute, even a little retro. But maybe my eye is messed up!
4) With skinny jeans adding a pointy toe heel just seems to elongate my leg that extra couple of inches I need to have the "ideal" proportions. My legs are average-length -- not really all that stubby (that's in my head, my tape measure says different). I can handle ballet flats but I much prefer adding a heel, activities permitting.
I did not know this was trashy -- never would have occurred to me.
