If you and your baby are happy then don't let them bother you!
I will say that I cheat... I let them make the comments about my lil Chi(Peanut) then ask them to turn around look behind them and tell DD's Ridgeback/Pitt cross(Denali) that her dress is stupid looking!
....hear the crickets chirping???
Denali MUST wear her outfits too and she also believes that her goal in life is to protect her "lil sister" Peanut! *sigh*
Seriously tho- you aren't hurting anyone and besides IT'S FUN!!
