Pronovias Semilla Size 6/8 For Sale

Here`s my situation... I bought a Semilla dress (no flower) from a friend of a friend who wore it at her wedding and it is in perfect condition. She bought a size 8, but had it altered down to about a 6 (we are both 5`8 and about 125 lbs, size 4 street clothes), but she had it altered in a way that no material was cut so that it could be let out back to an 8 if needed. I absolutely LOVE this dress, but my engagement was just called off and it kills me to sell it. Would anyone be interested in some sort of rental arrangement or buying it and then selling it back, so that i would be able to have it returned after your wedding? I have a hard time justifying keeping it at its cost, and am having an even harder time letting it go (as you know it is the most beautiful dress in the world and I`m afraid when/if I do get married far in the future I wouldn`t be able to get it anymore). Crazy request, I know, but if anyone is interested please leave your email address
