While each character Doctor has always had a different character, the clothes themselves always lend to that character in my opinion, and the clothing worn since the revival have added nothing, and in my mind actually take something away from it.
Eccleston was the worst in that his clothes were something that anyone would quite happily wear, and I would go as far as to say he was fashionable.
Now this may have worked, had the follow ups been a bit more flamboyant, to make his Doctor stand out more as the serious Doctor, but instead we get two more normally dressed, though less fashionable, Doctors.

They dont have to be as out there as Colin Baker but they should stand out from the crowd, even when on Earth.
