Sweetheart Neck Linen Blend Top

I'm usually an Open Edit x-small, had to size up in this one, mostly because the linen doesn't give AT ALL and the buttons strained a little across the bust. I'm a C-D cup, so might not be an issue for smaller busts, BUT, I also have a fairly narrow ribcage. In order for it to lay flat, size up. Otherwise, the neckline is classic and flattering, the armholes lay nicely, it's a lovely springtime top.
