I feel if Paul McGann reprises his role on television as the Eighth Doctor, I think any potential producer of the series should consider doing variations of his costume instead of having him wear the same frock coat, cravat and waistcoat attire all the time.

The Regency look. The clothing the figure to the left bears a close resemblance to the costume Mark Gatiss wore on Beeb Beeb Ceeb Two's Doctor Who night. I always thought this attire would work just as well for the Eighth Doctor. I think either the plaid get up that the figure is wearing or solid colours would work well. I also liked the eyeglasses that Mark Gatiss's Doctor sported as well (right). The Doctor has used the aide of some form of eye wear in the past, either a monocle or reading glasses.

Sort of like what they did for Jon Pertwee and Tom Baker's era's as the Doctor. Where they had a basic motif for the costume. With Pertwee it was the frilly shirt and velvet frocks. With Baker it was the long scarf and floppy hat. But would do variations on it.
