Madam Malkin's Robes for All Occasions:
Though far from the only wizarding clothier around, Madam Malkin's seems to be the best, as it is the place where most Hogwarts students purchase their robes. Madam Malkin herself is a friendly, squat witch, though she seems a bit out of touch at times and got flustered when Draco Malfoy confronted Harry in her shop .
Madam Malkin's is located next door to Flourish & Blotts, and in addition to selling Hogwarts school robes , they also sell robes which are "spangled, self-ironing, beautifying, slimming, fattening, lengthening," and "temperature-adjusting" and they carry robes made by Whopperwear "for the outsize witch or wizard." A later advertisement states that every robe sold at the store is "self-ironing and repairing" as well .
Madam Primpernelle's Beautifying Potions:
A company that helps witches remove "warts and worse," and that recently advertised for Junior Potion mixer in the Daily Prophet. Madam Primpernelle's is located at 275, Diagon Alley .

Ollivander's:
"Makers of Fine Wands since 382 B.C," Ollivander's is a narrow and shabby little shop with a window display consisting of a single wand resting on a faded purple cushion. Inside the walls are lined floor to ceiling with thousands of narrow boxes, which Mr. Ollivander chooses from when trying to find a wand to match each customer. Ollivander's closed in 1996 when Ollivander was kidnapped by Voldemort ; it is unknown whether he re-opened the shop following Voldemort's defeat two years later.
