We are so sorry that we will make the dress exactly the same as the picture shows, so we can not add the extra side sashes.
Every designer has his unique design with the fixed design and material he choose, if changed, it could not assume the same style as you see in the picture.
Hope you enjoy your shopping here.:)

Dear LQ,
The shown color of the dress in the picture is Champagne. We are sorry that this dress is not available in custom sizes due to its design. Please compare your hip, waist, bust and hollow to floor length measurements to those in our size chart [link to http://www.lightinthebox.com/html/All-You-Need-To-Know.html?tab=2] to determine which size will fit you best. It’s usually best to go with the size matching your largest measurement (bust, waist or hip), and to round up if you’re between sizes. This will leave extra room for movement and alterations if needed.
