The three times tomoko actually puts something on to look cute fails because she went to far with it:
-the perfume was ok but she applied too much to the point it smelled bad
-mama puts too much make up on her and she end up looking ugly
-the uses a short skirt and nemo makes her do an "ugly" scream at some point (or that's how it was depicted)
It as been known that she would look cute if she just covers her eyes as shown in one of the 1st chapters of the manga.
I want the watamote stuff to keep on comming.
