In canon, no.

IRL, RTD didn't want to deal with viewers laughing at David wearing "women's" clothes, even though Jodie's outfit was fairly unisex IMO.

I expect the size difference would have been more of a practical issue.

not as far as i know, but they did make a point of showing the master regenerate into whittakers outfit, so it is defiantly implied that there is something wrong going on here, but since the chrismtas special was cancelled, we likely will never know the original intent.

"Unstable Molecules"

The same thing as happened when Hartnell regenerated into Troughton.

Didn't Moffat establish (at Christmas, no less!) that the Doctor is naked all the time and the clothes are just virtual? That explains the change during 13-14 and how the old costume fits a new body with an different build during other regenerations. No idea why they look raggedy after a change.
