When you and your mom buy the same lingerie set

Compliment her on her good taste!

My wife's mom bought my wife's lingerie for our honeymoon, and she did a great job! A sheer white baby doll for our wedding night and other good stuff for the other nights. Thanks Mom-in-law! She obviously had experience buying sexy stuff.

Guess that means you both have good taste

maybe different sizes so you don't mistake them🙈
