I know in some cases Morning Musume used their budget wisely and gave the girls more then one outfit (ex. Mr. Moonlight, Koko ni Iruzee, and Onna ni Sachi Are) and anything pre-Love Machine was just hip and cool Rocker Musume being mature and crap so they really don't count and they were never "costumes" as they are today. So rank according to either single cover outfits or PV outfits.
And if you DO pick a PV outfit from a single that had a alternate cover image, how did you feel when you were jipped? Mr. Moonlight had this awesome space theme and then WTF we're going to swing into the 50s?!, or Koko ni Iruzee, I wanted flying nurses and all I got were some grimy military outfits!
In my case, Morning Musume has NEVER EVER worn a gold or yellow outfit I have ever liked. Ever. Four way tie between The Peace, Osaka Koi no Uta, Onna ni Sachi Are PV and Triple Word Score 47th Single for worst outfits of all time.
