D is not just a tailor, the man is an artisan. The quality of his work is unmatched and he has a great instinct for giving advice on modern menswear.
Be warned, he is not the cheapest, not can he deliver a three day turnaround like some of the franchises will (these are both good things - you get what you pay for!)
While other tailors deliver cheap, sloppy work on a faster timetable - D is in a class of his own.
