2 weeks out, just want to elope.

Hey guys, Sorry I haven't posted in so long. So it's getting down to the nitty-gritty, 2 weeks away from I do. Things can't be any worse. Yesterday a tornado ripped through our beautiful two-acre backyard which is our venue. It destroyed everything including my SO's separate office/shed building tearing it to pieces. It's a disaster. But whatever right? We'll clean it up no huge amount of damage done. Then I pick my dress up from the seamstress, It looks beautiful but now with the alterations the dress gives me a back vagina, it looks gross and I feel so insecure now, even so whatever my long hair and veil will cover it up fine, then I notice a huge yellow spot on the left lower side of my dress, I asked the seamstress about it and she said it was like that when I brought it in the only problem is I haven't taken it out of the dress bag since I got it and it's been in my office closet so nobody and none of my animals had access to it. It looks as if a dog or cat hiked up his leg and pee'd on it. Even worse I smelled it and can confirm it's pee. The seamstress denies having any animals around it and refused to clean it. How do I get this off of my dress by myself, after alterations it's not in my budget to have it dry cleaned again, or should I just get over the budget and take it in to be cleaned anyways? Any help is appreciated. How is your wedding planning going?
