I sweat pretty easily, but after 3 sinus surgeries I can't smell a dang thing. So I depend on my poor husband to say "um, honey...." haha! But ever since high school I've been using CertainDri (available OTC at target/walgreens etc) which essentially closes up the pores under your arms. You put it on at night once a week or so. It's the only thing that works for me.
