PILAC stands for "Potential In-Law Approved Clothing" and refers to the a certain style of clothing that is appropriate to wear in front of your significant other's parents. PILAC mainly refers to not wearing anything that is too revealing or too tight. It also refers to the inclusion of a cardigan sweater with every outfit.
I am shopping for a cardigan because I need to update my PILAC options.

The only time I wear turtleneck sweaters is when I need to dress in PILAC.

This outfit is so PILAC and classy.
