I think both dresses would look beautiful, but if you already have a dress you love, why not keep it? If you are worried about the off-the-shoulder style being similar to his ex'es maybe you could take it back to the bridal shop you got it from, and for a small fee, have the straps taken off. The bridal shop I am working with told me that pretty much any dress that has staps, they can be take off, and pretty much any dress that doesn't have straps can have them added.
