Pairs Well with the Davids Bridal Dark Green
Me and my husband were bridesmaids and groomsmen in a wedding. The vest was nice. It has a good color. At first in the packaging it looks darker but once you pull it out its lighten. I was wearing the dark green thats from davids bridal and it pairs very well with it.

Can’t be beat for the price
Size: XX-Large, Color: Blue
Can’t beat it for the price, I was at super fancy NYE party. Lots of guys in very expensive jackets asking me where I got mine, this jacket got tons of compliments and looked great in photos. Quality was higher than I figured it would be for this price point. Go one size up, I am normally an XL, I ordered XXL and fit perfect.
