I genuinely can’t wear a dress or top twice in summer no matter how much deodorant I put on. I don’t have terribly BO but anything that touches my armpits all day doesn’t smell fresh.
I have to put a tight top underneath the dress to keep it fresh but that often spoils the look if the dress is at all low cut or has short arms or is tight. Even in winter I do this to wear the dress more than a couple of times.
I’m always frustrated there aren’t more tops for sale cut so that they can be used like this without showing - but maybe there aren’t such tops because others do not have to wear them. Do you?
