Always love the cut of TR briefs, high waisted and high legged look great on my shape. But I bought a S this time as the medium bags a bit round the waist, however the S is a little bit uncomfortably tight. I am a size 12 for reference but think the fit issues may be my shape rather than the briefs. If you are pear shaped with a small waist, I would size up to fit your bottom half rather than size down to fit your waist
