HELP: MAGGIE SOTTERO Sash Alterations

I found a dress that a I want to buy, but the sash is the wrong color! It is the Maggie Sottero Jessica diamond white with a rose/pink sash. Is it possible to replace the rose/pink sash with a different colored one? Also, I noticed that there is beading on the sash (centre front) and beading on the back (at the top of the chapel train). I can take the beading off on the sash (if pink), but I think it would be too much work to replace the beading (if it is pink) on the chapel train. Has anybody seen this dress in person or have this dress?
