Dressing as a teen

When I was a teenager 13/14 I used to dress up in girls clothes secretly in my room. One day I was caught by my mom, she took in clothes and altered them at home to make a bit of money and she realised I had been trying a few things on. Instead of being mad she got me to be her mannequin and I would wear dresses and she would pin them up before altering them, she knew I loved the dress up.
Mum made a bra with filling and a back on for me to wear so the clothes hung better when being altered, she knew I would wear this at times outside of helping her. She said to me if I wanted a boyfriend to be careful and be nice.
