I love this thing! I put it on my bra to see if it would be annoying to wear during the days when I'd need it, and completely forgot I'd had it on until I went to change for bed that night. Very soft on the skin, not scratchy or obnoxious. I've been wearing it the past week or so while I've been traveling in the UK and I can fit quite a lot in it. It expands a bit so if you wanted to really cram stuff in there you probably could. Solid investment. I like knowing I have extra cash and cards in a discrete spot.
