The only time I ever told my villager the shirt they get doesn't look good was the time someone gave Olivia a moldy shirt. She still put it on anyways, and is slowly spreading it around my entire town. ._.
I have no problems saying they look bad. I believe that not every top works with every villager. Example, Eugene. I think he only looks decent in most black tops and nothing else.
If I don't like the way they look and they insist on keeping it on, I'll quit the game then restart, open up the gift, and throw it in the trash.
