She looks a lot better without those imprint marks that her necklace left when it got stole in 1F09 "Homer the Vigilante". They're clearly non-canonical anyway, since Bart removed her necklace quite easily in 5F08 "Bart Carny".
Sorry, I had to unleash my inner Simpsons geek. Great stuff!
lol I think she looks hot without them, Remember the episode where Bart took them off and to be honest she did looked naked without the pearls, Probably is the habit of watching her with those on every episode.
