Something that doesn't sit right with me when the Thirteenth Doctor regenerated into the Fourteenth was how her clothes changed. The Doctor's never been able to generate clothing out of thin air before. Why couldn't the Fourteenth Doctor have appeared wearing the Thirteenth's clothes? After all, she first appeared wearing the Twelfth Doctor's clothes (which were too big for her, being 16cm shorter than her previous self). Almost every other Doctor (and Time Lord) regenerates wearing their predecessor's apparel.

Which begs two questions:
1/ Why has no Time Lord ever regenerated clothing before?
2/ Why didn't the Doctor generate a second set of clothes when he bigenerated into the Fifteenth Doctor?

I actually quite like how the Fourteenth and Fifteenth Doctors split their clothes amongst themselves. It makes sense; your body has just doubled, so your clothes are now divided between the two of you. Fourteen has no shoes and Fifteen has no trousers etc. (Fifteen got a better deal than when the Tenth Doctor spawned the Meta Doctor in the buff!) I like how they paid attention to this detail. Which just irritates me even more than they completely ignored this when Thirteen regenerated into Fourteen! Gah!


Most incarnations of the Doctor have made his/her first appearance wearing the clothes of his/her predecessor. Exceptions being:
* Eighth Doctor waking up naked in a morgue.
* Meta-Crisis Doctor generating naked (since he spawned from a spare hand of the Tenth Doctor).
And that's it. Either way, none of them created their own new clothes out of nothing.
