For sequins you could use a little cutter and dust them to match, how about edble jewels?

Would actuallylove to do a cae designed on the dress, so much scope to work with

Either of those ideas will work. You could pipe in royal and paint with a luster dust paint when dry.

I've done that dress, but in lavender. I used glitter gel.

thanks, ladies. cherylweddingplanner - if you do make a cake based on this design, please send me a pic!! That's the dress my sister has chosen for her wedding in August... I'm going to play around with these great ideas (why I never thought of luster dust.. I'll never know! It's like the miracle powder! And glitter gel?!?!... ingenius).
