Anyone know if these Suspenders stay put?

I assume that they should sit on the nipples but they probably will not stay there without purchasing some double sided tape. Sadly, there are no reviews on this yet since it's rather new. I would have purchased this if it wasn't for the really (in my opinion) awkward hole at the butt crack of the panty. That ruins it for me. I like the suspenders a lot. They're cute.
