Zara Pearl Button Cardigan in Butter Yellow

Zara Pearl Button Cardigan in Butter Yellow Light Yellow / Butter Yellow Size M Pearl buttons that don’t actually unbutton. They have a seam that closes it shut but still has the look of a cardigan. Very cute but too small on me (I'm typically a size 8/L in Zara). I cut the tag off but I think this is some polyester blend. Soft/slinky feel.
