My wedding was in New Orleans (full vendor reviews posted on that board), but I did use a couple Dallas-based vendors and wanted to make sure that I gave them their due since they were both fabulous!
INVITATIONS / ALL PAPER GOODS: Stamped Paper Co. (stampedpaperco.com) - A+++Stamped designed GORGEOUS custom save the dates, invitations, and a full suite of paper products for our wedding that just took my breath away. They were so unique, fun, and beautiful, and just completely captured the spirit of New Orleans and of our wedding. Jill is a creative genius who will work with you to find the perfect visual representation of your event, and she is amazing to work with. People raved about these invitations, and multiple friends confessed that they decided to make the trip after they saw how beautiful the invitations were and knew it would be a great event. Cannot recommend Stamped highly enough.
DRESS ALTERATIONS AND VEIL: Bridal Collections by Stella (www.bridalcollectionsbystella.com) - A+I purchased my dress in Austin, but wanted to use a local tailor for alterations so I wouldn't have to drive back and forth a bunch of times right before the wedding. Bridal Collections by Stella was recommended to me by the bridal shop in Austin and I am so glad I found them. Their alterations are amazing - they turned my A-line lace dress into a form-fitting mermaid that fit my body like a glove (no easy trick when you are dealing with lace!). It was a little pricey, but it was also a great deal of work, so I didn't mind. They also helped me select and order the perfect beautiful veil for my dress, and they were very nice to work with. Great little shop!
