    Supportive
  

*by M***T on Reviewed in the United States on June 10, 2023*

I usually use the regular Amazon 3 pack, but decided to give myself an upgrade. I’m impressed, they have a bit of extra firmness/support in the front, I really dig that. I’m glad I ordered all of the colors. Fit is a comfortable-snug.I’m 41 almost 42, size 16/18 U.S. I ordered size 2.I wear these and I use a cup during my period. No fuss no muss!
