MontelleHookedUp Shapewear Women's High Waist Shaping Brief 3X Black

Hips 52.5" , waistline 36.5-37", so what size for me??

I wear a size 6. My bust is 38, my waist is 31, my hips 37. What size shaping brief should I order?

Can you hook it to a sports bra?

Could the hook go on the loop where a detachable strap loop on a strapless bra goes?
