Madam Malkin is a squat, smiling witch wearing mauve robes. Madam Malkin's robe shop is next door to Flourish & Blott's. Hogwarts school robes are to be found here.

People are fitted into robes, with enchanted measuring tapes and other such items zooming around their head. It's quite the amusing sight to see a Mr. Ronald Weasley getting fitted for dress robes at the start of the school year.

During one summer sale, they sold robes which are spangled, self-ironing, beautifying, slimming, fattening, lengthening, temperature-adjusting, and plain, with a free frog-skin belt with every purchase.
