This could potentially be the only bag you actually need, it ticks all the boxes. The shape is timeless, its kind of hard, as in things will be safe inside it. It has a zipper pocket inside, and the strap length is adjustable. And its a functional size.

As a mum of 4 young kids, I genuinely forgot how nice it is to have a handbag that doesnt need to fit wipes and the rest of everything, this bag is nice for when I only need to look after me.
