There are four shirts that I want to mix n match.
#1. Do mix n match the shirts with jeans and high heels. Very simple but look nice.
#2. Short shirts can be matched with sweater or cardigan. If jeans are boring enough, do mix n match with long skirt.
#3. Formal long shirt that usually wear at the office, do mix n match this kind with short pants. Look boyish, like daddy's daughter.
#4. Girly shirts can be matched with short skirt.
