Just googled “magical boys” and came up with this:
Obviously the outfits of the blue and green boys are actually decent (prefer the green one, as he has actual boots).
Yellow isn’t too humiliating, except for the fact that I loathe shorts (anywhere but on a tropical beach/resort).
Red wears what looks like an embarrassing school-boy outfit with way too short shorts and pink is, of course the most humiliating as it’s red’s school boy outfit with the addition of what looks like high-heels and a more feminine cut of the shorts and jacket.
On a related matter, what happens to someone’s actual clothes during transformation? Are they disintegrated and lost in the void forever? That would be very embarrassing upon de-powering and also very expensive and would likely prevent our heroes from owning nice clothes.
Are they transported to the magical boy/gir’s home or base? similarly embarrassing upon de-powering, but at least you could afford to own actual nice clothes.
Or do they actually transform into the silly outfit and revert back on de-powering?
