Summary: The Doctor has one accessory that goes with anything.
His style has changed many times over his regenerations. There’s been velvet and lace, long scarves and floppy hats, umbrellas and pullovers, cricket whites and celery, suits and sneakers, jeans and leather jackets, tweed and bowties, even a fez or two. The Doctor always knows what looks cool; he’s an intergalactic trends-setter with his own unique sense of style, oft imitated but never bettered. It’s a good thing the TARDIS contains such an extensive wardrobe.
But no matter what eclectic outfit he chooses to wear, there’s one thing he’s never, ever without. He simply feels undressed without his trusty sonic.
