Five Stars for purpose I purchased it .  Lightweight, not hot at all, fitted sleeves that will stay up when rolled or pushed up.  Neckline is really cut low, below the top of my granny bra, in fact... but I like that because it will not show when I wear it under a scooped or V neck.  I really like this ttop for layering.  It is also smoothing... opaque without being thick.
