I wish I could take credit for coming up with this gift idea for your favorite bride, but instead I will just share how adorable it is. After seeing it on the wall of my favorite bride/new mom I had to find the Etsy shop that it came from. It was a present from one of the other chic bridesmaids from her wedding and I only wish I would have known about it sooner. It would have made some after-wedding gift giving a lot easier.
This Etsy shop makes customized illustrations of the wedding dress and will incorporate any other elements you might like to add. From bouquet flowers, to a quote, to an accessory, she will make it happen. The above is the exact print of my friend.
I can say from seeing it first hand, that it looks great as part of a gallery wall of wedding or other favorite moments. It would be the perfect gift to send a month or two after the wedding madness so that your friend can enjoy her dress every day in a totally different way.
