I have 4 DDs (hence the nickname!). The younger 2 are 10 and 12.
Shoes tend to be Ugg boots, brightly coloured Vans pumps or flat ballet pumps. DD4 has ballet pumps with a strap for school, DD3 has just got a pair of the lace up/jazz shoe/brogue style ones.
For casual wear they live in skinny jeans (coloured or denim), denim shorts, wool shorts over tights, leggings (almost always black), short skater style full skirts. This is paired with vest tops and long boyfriend cardigans, cable knit jumpers, off the shoulder sweatshirts, printed t-shirts with pictures, hoodies (Jack Wills, Abercrombie and Superdry are favoured). DD3 has a body-con style short mini skirt she wears with tights and jumpers.
In terms of if we need to look a bit smarter or they're going to a party they favour the Johnnie B style dresses with the vest and skirt combined or t-shirt style dresses. DD3 has one prized dress from Jack Wills (like this one: jackwills.com/en-gb/product/oxenford-dress-014988266 but slightly different pattern) but fortunately sadly most of their stuff is too big still. Playsuits are favoured too, usually with tights underneath. DD4 has a really cute little navy blazer from Zara that smartens a lot of things up.
For winter coats they both have gilets (with the fur hoods!) and a warmer coat. DD4 has a padded number - Barbour style, but actually H&M! DD3 has a Jack Wills padded one, Barbour style too. DD3 has a Zara wool peacoat too which she's had for years but hasn't grown out of. That tends to come out on smarter occasions.
DD4 doesn't really do accessories. She has a knitted scarf, hat and gloves set for the depths of winter but isn't fussed. DD3 has some bits of jewellery - mainly coloured bangles and faux-pearl bracelets. She loves her big colourful pashmina scarves and her chunky cream knitted scarves. They both have the cross-body satchel type bags - a big one for school and a smaller one for weekends.
Shops wise we favour H&M, Zara, La Redoute, Johnnie B, Mini Boden, Abercrombie, Hollister, Jack Wills and actually M&S!
