Heh its just the fatness, eat some celery
Also, too make her look better, just get a hair cut.
Also it depends..is your character Corrupt? Because being Pure makes your character way better looking.
But I am almost 100% sure it is fatness <_<
Celery is basically all you need, what you do is, go to the produce store in Bowerstone. Buy the celery there, sleep 7 days, buy celery again, sleep 7 days, buy celery, and repeat and repeat about 5-7 times? More depending on how fat you are lol.
Hope this helped
