With the rain both my girls umbrellas decided to pack it in. They have my Taylor Made umbrellas for this bout of rain but they’d prefer something smaller and girly.
Totes seems to be decent but I am not sure about non golf umbrellas https://www.totes.com/collections/umbrellas/products/inbrell…
Coles sell a small portable umbrella that I keep in my work laptop bag. It's fit for purpose.

Or IKEA like someone said above. They're kids so their umbrellas will get crushed eventually by their school books and you'll need to replace semi-regularly. Your site seems based in US so by the time you get them rains all over (+FX conversion)
$2 shop. Got one yesterday for school bag.
There's some 'girly' ones on sale today only at myer https://www.myer.com.au/search?query=miss+shop+umbrella
