I finished the Snow White dress for my DGD and she has asked for a Belle dress next. It came out very nicely and has a 3 inch double hem for letting out when she needs the length. I've posted a photo of her trying on the dress when I was checking to see if the sleeves were a good fit. She wanted to wear the dress at that point so it was a couple more days before I could get the arm bands attached. The rib knit worked very nicely for the arm bands. The velcro at the back waist wants to come undone when she is very active so I may try something else there. (I thought velcro came is different strengths for different uses but I could only find one "sew on")
She loves the dress and even though her height (37 1/2 in.) matched the approx height listed on the pattern envelope I'm glad I checked and cut the fabric 4 inches shorter. I used another 6 inches for a hem and the pattern only called for a 2 inch hem. I've had other problems with Simplicity so I'm glad I've learned to check.
