Was this outfit too simple for my sister’s engagement?

This was the last moment outfit I wore at my sister’s engagement. I paired it with diamond earrings and rose gold chain and a bangle. I was told by couple of my relatives that i looked too simple for an event. Since then I’m wondering what can I change as I was thinking to go with similar type of sarees for her wedding.

Saree and blouse: (got stitched) from local shop at itwari ngp
