Approximate measurements lying flat:

Armpit to armpit 16"
Length 21"

This beauty has been around the block a few times but still looks uniquely fantastic. 
The brown beaded lace strip underneath the embroidered section of the v-neck has several beads missing, however, because they are small seed beads and that section of fabric is shimmery missing beads go unnoticed. 
Please enlarge photos and review carefully for best indication of condition.
