Those are iconic tie espadrilles. Very chic. Classic resort wear, your mum was everything in those shoes.
It's a shame I can't show the whole pic, but both her and my aunt were wearing espadrilles and they both looked gorgeous. At sunny Bournemouth on the UK South Coast no less, back in the late 50's with no babies or mortgages, just new husbands and a whole life ahead of them.
Alice isn't a "quirky" dresser, she just doesn't have any taste, or any idea of what looks good. My mum, 5'2" and on the curvy side, realised that she looked better in skirts than she did in trousers. I'm the same height but with no curves, I've always been a jeans and t-shirt girl.
Alice has model height, but she's quite broad and so needs to soften her outline with fabrics that drape and flow. We've said it hundreds of times, but a decent pair of wide-legged trousers and an unstructured jacket, in soft colours, would look miles better than those weird cropped-sleeve jackets and bizarrely-shaped skirts that she's so fond of. And no woman over the age of 45 should wear too much black, it looks great on a skinny teenaged bottle-blonde, but it's just draining on everyone else.
And ffs, she needs to sort out her ghastly hair. Deep, deep conditioning treatments at least twice weekly (any old conditioner and a plastic cap worn overnight will do, she doesn't need to visit a Hollywood hairdresser

) and a decent wig whilst her hair grows out.
She doesn't have the imagination to be quirky!
