Oh my goodness (!) I agree with all of these complaints wholeheartedly!
I think I might be responsible for kicking off the costume whinge last night 
Maybe they ought to do a theme week "Vintage Strictly" and see if it catches on:
No props (just dance ffs!), appropriate music, glamorous frocks and as pp said, men in ballroom tails or black trousers/stretchy single colour shirt for latin! 
At the risk of sounding like Len, I don't understand why producers felt the need to fix something that wasn't broken. They were getting the ratings, Strictly was overtaking XFactor - why did they need to "appeal the the yoof" (none of whom are interested in this cringey wacky stuff I'm sure - teens I know have better taste). The budget must be enormous (going by the judges' and hosts' salaries
) - give some of it back to wardrobe 
Over time I've muted increasing amounts of the show. Tess, judges (including their entrance), VTs, adverts for ITT, scores, Clauditorium bits are all on mute lest I cringe myself inside out. That only leaves the dances and the contestants entrance down the staircase at the start. I'm barely even watching them anymore as the quality is so reduced it makes me cross.
My other massive peeve is that the past series are unavailable on iplayer etc. WHY?
(all I can think of is music rights, I don't know how that works)
I could probably cope with present day dumbed down Strictly if I was able to watch the old series (esp. 1-5 that I missed).
