Tucked away in little Juniper street, just off Walnut and smack in the middle of Center City, is Royal Custom Tailor. The service here is FANTASTIC. You are immediately greeted by the tailor himself. Besides making custom men's suits, he also takes on smaller jobs - hemming and the such. He has a great eye and is not afraid to make suggestions regarding length and fit. I've had pants, suits, and even a coat altered here, with great and quick results every time.
