I gave this bra a try for mulitple wears and finally ended up throwing it away.  It was not the fit...which was good and in keeping with Champion's fit.  It was sharp tiny "thread" on the seam just above the breast others have mentioned.  It not noticeable until you actually attempt to work out in it and then the friction literally feels like a piece of steel wool in your bra. I could barely run with it on and when I took it off I would have a red irritated mark on my chest.  I tried to shave the spot, washed it in hot, trimmed with a scissors...nothing.  The weirdest issue I have ever had with a item of clothing.  Worse is you can't see anything on closer inspection.  Its as if the thread itself is made of fiberglass.  So ODD.
