Heres the dress picture I promised.
This is my DDs dance dress for her dance recital. The color isnt really great - she was on stage. Its actually a teal color that is very dark teal, depending on how the light hits. This started out as a one piece dress. I converted it into a top and skirt and added a black fluffy necklace (with lots of bling). The skirt opens down one side for ease in getting it on with the wheelchair.
This dress had no waist, which made it more challenging to make into a top and skirt. If it had a waistline, I could have just taken it apart along the waist and made it into 2 pieces. Since it didnt, I had to decide just where to cut it to make the top so it would be long enough to cover the top of the skirt and DDs wheelchair seatbelt. The top has slits in the side seams to hide the seatbelt.
I also had to remake the top to some extent because it came down too low (one of the reasons for adding the neckpiece with bling).
I also had a challenge to make it the right length - hard when the person who is going to wear it cant stand up. Her sister tried it on for me, but older sis is about 5 foot 6 and younger DD is only 5 feet tall. That led to some figuring out.
