DVMMOM- This is an age old problem.
I specifically remember my mom being distraught because I wanted to wear oversized sweatshirts, leggings and slouchy mismatched socks in the 80s. Nothing immodest about it, but she said I looked like a clown.
Then in the late 80s when it was bleached/ sugar washed pants, with holes in the knees, and neon, and suspenders and oversized blazers with shoulder pads, poor mom was distraught again, she said I looked like I didn't know how to use a washing machine, and there was no way I was going to go about town with bleach stained pants. The sprayed out hair was gaudy too, but nothing too immodest.
In the early 90s, it was grunge. Ratty t-shirts, ratty flannel. No immodesty, but mom hated that I looked "like a hitchhiking lumberjack."
I remember she didn't care for the super wide legged jeans that came into fashion when I first started college. (not immodest either, but she said she couldn't understand why we took our style cues from elephants).
If mom had her way, I would have been in business casual, slacks, loafers/ smart slides or kitten heels, sweater sets or a modest skirts, paired with a 3/4 length coat, and a chain of pearls from age 12 on.
Took me 20+ years until my wardrobe choices aligned with her preferred look for me.
Good luck to you and yours,
F. B.
