I saw this style of dress/gown on Patty Bennett's blog and then found a similar one on StampingSharon's blog. I just love these and made a robe to put over my dress. I am hosting a lingerie bridal shower for my oldest son's fiance. I thought it turned out so cute. I made another pattern from vellum of the dress and drew a line at the waist. Then I used a ruler to draw a line from the center point of the waist to the 4th scallop from each side and cut that triangular shape cut. To make cutting all the dresses and robes out, I just held the pattern to each scallop circle and freehand cut around the pattern. I felt it would take too long to trace around the pattern each time. I had to do a little trimming after adding the robe over the dress, but I think they turned out so cute.
I made the inside on My Digital Studio. I love how easy it is to match the colors to the card stock. Great way to customize your invitation.
