I sweat a lot even when I am not working out mostly under my arms and palms.?!

This happens to me also. The only reason I can think of is that maybe our pores are just big, so we sweat easier. If you were a lot of thick clothing around the area that you sweat the most, that might be part of it also. I advise you to just use a lot more deodorant than usual. I do this and it's not nearly as noticeable. You might also want to refrain from wearing really light colors because they could stain, so it's much more apparent. I cannot tell you how many times I've been on a date wearing a white cotton dress only to go to the bathroom to discover that there's this huge stain underneath each armpit.
