It’s mixed at my school:
The country ones are: F and F knee boots, tucked in jeans or short skirts with tights, cashmere jumper, tweedy fitted jacket, blow dry or nice messy bun.
The gym gear ladies: usually bright colours, usually lulu lemon
The going to the office ladies: wide legged trousers, silk blouses or cashmere, proper wool coat, nice bag
Others: mostly jeans (wide leg), cashmere jumper, adidas suede trainers in a coord colour, wool coat. Very occasionally; flowery dress, oversized jumper, ankle boot, messy hair.
Cool city mums: all black usually with jeans, black DM style boots, sharp haircut which is then roughed up a little.
dads: usually chinos or jeans, smart trainers or boots, shirt, jumper, jacket or proper coat
No pyjamas, track suits, puffers, black leggings, dungarees, boxy quilted coats, walking or outdoor clothes, fleeces, lounge wear.
