10. Peri in the Mysterious Planet
Peri was not fortunate to have many comfortable outfits, and the only ones that were decent were from the episodes Timelash, Revelation of the Daleks, and then this one from the Mysterious Planet. While I find the stripes bear a resemblance of the Sixth Doctor's own costume, Peri did have a snazzy pair of gray-blue trousers and a golden-yellow deep cut blouse. The problem Peri had throughout her run in Doctor Who, and most people actually adored her costumes, but there were a few that were obviously close to being too small (ie The Two Doctors, so the solution was to adding a jacket over the bikini top.) Another atrocity of a costume was from Mark of the Rani, where it looks as though Peri is ready to go clog-dancing. So the Mysterious Planet outfit had more a comfortable look to it, and Peri looked very pretty in it, and her longer,styled hair certainly improved the look a little bit more.
