To get the best results i had to size down. I originally ordered the recommended size but returned and sized down.

Thank you so much Steven, hope you enjoy your Lift Briefs :)
Incredible Quality - run a bit smaller (as expected for a good lift)
Incredibly discreet. High quality. Great Lift. Got a size up and fits perfect with good lift. Lots of compliments
