Help! has anyone ever made these adjustments to their gown?

Hello everyone, I have found my gown but I'd like to add Swarovski crystals to trim the bottom of the dress or some type of applique, just to make it a little different. It's an Eve of Milady dress I will post pictures soon but I was told that the designer doesn't make these kind of adjustments to the gown. Lestan's has the dress and they say they can do the adjustments if I buy the applique or crystals. Has anyone ever done this before? Can anyone tell me where to go to get these items?

WELL NOT THOSE TYPE .. BUT MINE IS CURRENTLY GOING UNDERGOING SURGERY ..REMOVAL OF THE COLLARBONE(halter) AND MAKING IT STRAPLESS.. I WILL BE ADDING PEARLS TO THE BOTTOM..BUT I'LL SEE IF I SEE MORE OF WHAT U NEED

I'm adding swarovski crystals to my dress too. All the bridal salons usually do this upon request. You just order the dress from Eve of Milady and when they receive it they'll add the crystals where you want them. Its like customizing your dress. I know anotheer bride that added all different crystals to her dress and practically changed it from its original state. You can do it!

Thanks. I was thinking of doing that but the woman at the salon told me to get the crystals and she would have them put on. I already have her adding buttons to the dress so I guess I will ask her to just add the crystals as well.
