I think some pps are being rude...
A runway model/cover of Vogue/ Victoria's Secret etc...yes most likely that ship has sailed.
But I know some friends who were in local Beauty competitions and did promo work (Grid girls etc) in the 00s but who never got to the level they wanted and who after becoming mums were surprised to discover that doing a bit of modelling on the side turned out to be more of a success for them in their 30s and 40s than it ever had been when they were late teens and 20s.
They've had catalogue/clothes website work, ads and commercials both on TV and in magazines for things like DWP info for tax credits, washing powder/cleaning products, formula milk and nappies, Tesco type adverts where the whole family is involved. One of them is one of the most recogniseable plus size models in the world now and spends her life between NYC, California and the Far East...modelling for companies like ASOS, Bravissimo, Lululemon as well as small companies, wellness brands and, occasionally, big designers/runway work. She's 40 and a size 16 but utterly stunning...face like Natalie Portman, blonde, tanned. You'd not know her name but you'd absolutely know her face.
All of them were classically very pretty, some of them have had a bit of Botox but no more than that. They fit the "pretty, kind, Mum" sterotype now and companies like Fairy, John Lewis, Dove and Prima Magazine are always looking for that sort of woman. Most of them are size 10/12, have taken care of themselves, shiny long/mid hair, good white teeth, good skin but no fake fillers/boobs etc. Being fabulous with babies and children on photo/advert shoots has also got them a long way even if they don't have kids. Think the sort of woman you'd see in a Pampers commercial or modelling Skechers sportswear. Look good glammed up or dressed down in jeans and trainers.
Most of them also occasionally do TV Extra work or supporting roles - I've seen a few of them on soaps when there is a parent and toddler group or child's party or on a hen night storyline. Sometimes they model clothes on programmes like Lorraine or This Morning.
I don't by any means meet this description but I don't sneer at women that do,
They make good money from it as a "side hustle" and still get to remain anonymous and have a normal life.
