I would go with the pink and to keep it from over powering the Sues, I would add cornerstones using all the fabrics from Sue's dresses.
I just made a pastel SBS quilt for my 8 year old granddaughter and I used a soft pink paisley print for the vertical sashing and a tiny floral soft yellow print for the horizonal sashing and used all the pastel colors of the Sues for the cornerstones. It turned out beautiful and she loved it. I failed to take a picture before gifting.
