Review (1/5): Great idea, failed experiment
These pads are supposed to stick to the inside armpit of shirt or blouse. They might do that on some clothing, but if there are seams, it's less likely. Also they make noise. Small and very thin pads so if you have severe sweating these will not be what you are looking for. Perhaps they would work on a tight fitting garment for a temporary situation like a wedding dress? But I'd have my seamstress create custom ones for me in that case built into the dress to remove later. Not returning because I opened the package, but I don't think you should invest.
