This is Hot Patterns Hot Cha Cha Cha No Sweat Easy Sew Halter Dress with some modifications. There is another style of dress included in the pattern so I did a little mix and match. I added the back bodice of the other dress and then altered the lower back pattern piece of the halter dress so it would fit together with the new back bodice. I did end up gathering the bottom of the back bodice to make it fit to my lower back piece. That worked out really well as there is gathering on the front bodice also. I put a zipper in the side seam so I could get in and out of it. I added 2 inches in length and now it hits my knee perfectly! I am happy with the way this turned out but I do need to make a few small changes on the next version. There will be many versions of this dress! So fast and easy! I cut and sewed this in about 3 hours or so on May 19th, 2008.
