Vintage Levi's 512 Petite Slim Fit Tapered Leg Light Wash Mom Jeans 4P

These are my dream jeans but they are too tight for me and I never wear them and these babies deserve to be seen!! The size on the tag is a 4 petite but they run small (see measurements in pics). I'm usually a 0 or 2 in pants and I can get them in but they are TIGHT. There is a spot on the back of one leg (shown in last pic). I didn't notice it until I took these pics, I don't know if it's a stain or a bleach spot. It isn't super noticeable. One leg opening also shows a spot of wear (see pic). I'm not sure how old these are, I bought them at a vintage store. I tried to adjust the color of the first pic to make it as accurate as possible, but my phone is pretty shite so the color may vary slightly. They are definitely a lighter wash. Zip and button fly. 100% cotton.
