After speaking with my dress designers I have decided to wear my origanal dress that I bought . I was worried that it would be too warm for a beach wedding. But they have said I can take the underskirt out and the bones in the bodice and it wont loose its shape, it may hang slightly longer.
I have a friend who's a seamstress so I think I might get her to take a look at it. I did buy another dress but felt abit sad that I wouldnt be wearing the one that I originally fell in love with.
