Can Bodyline's Antique Clock high-waisted skirt stretch any?

(It's L305. I'm not sure how to get the exact link.)
I think it's really cute, but the only size they have is M, and it's max is 74cm, but my waist is 76... Can it stretch that much, or should I hit the gym? (Or will the other sizes restock?)
