Where to buy women’s large shoes, appropriate for job hunting

Hi I’m looking for ladies shoes that are at 27cm (26cm at the very least)

And they have to be appropriate for job hunting so like pumps or flats

But I swear I can’t find anywhere that does shoes that big, and plain enough to be good for that.

The ones I saw at H&M seemed too casual, why japan gotta have such small shoe sizes😭

Anybody know any other stores I can check?
