how do you deal with...

All this anger over your MIL commenting on your wearing a hoodie more than once - oye ve! Hun, don't dwell on the small stuff - it'll drive you crazy and is just a waste of energy. Unless your MIL is lying about something important, i.e. about something you said or did that impacts your relationship with your husband or the family, and reflects poorly on your character or habits - let it go. To complain to your husband about something like this makes you seem petty and as if you're being overly sensitive and critical of his mum. It's a no win situation.
