Who doesn't wear short shorts?

Kourtney Kardashian!

The 30-year-old reality TV star -- who welcomed son Mason last December -- sported Forever 21 high-waisted shorts the other day while visiting her Dash boutique in Miami.

But she doesn't care if people think she's making a faux pas.

"I have seen some people say i look like a 'mom' in them or that high-waisted shorts are 'mom' shorts," she wrote on her website. "Well guess what honey, I am a MOM! Thank you very much."
