The problem with the classic Doctors' clothes is that, progressively, they stopped being clothes and became a costume.
Right up until Tom Baker, each Doctor had his own style - but it always looked as though he was wearing something he had thrown together from genuine clothes. It never looked like an actual costume.
Until
Peter Davison.
The 5th Doctor's outfit looked like a costume. And poor old
Colin Baker's outfit was exactly the same as Davison's only in horrible colours. You want to complain about the 6th Doctor's clothes? Well, it started with the 5th Doctor!
I think McCoy and McGann had a more subtle look by comparison to Davison and C. Baker, and the same for Doctor's 9, 10 and 11. Perhaps Matt Smith's clothes began to look a bit costumey towards the end, but over all the Doctor's look has been 'clothes' rather than 'costume'.
I hope Peter Capaldi is the same - just something that looks like clothes!
