It is this summery top . I have it in the red.
Looks a bit frumpsville in the pictures but tried it out of desperation as a replacement for vest tops/tees in the summer. Am wearing it today with dark jeans and a red cardi and it looks fab :)
Fits beautifully across the bust without any gaping (there is a neat little stitch keeping it together). The bottom half is relaxed fit but not baggy/tunic-like so very flattering as skims but doesn't swamp you with fabric.
Reviews are good for all sizes too.
