Best of luck!!Asking you to pay for dry cleaning?! ***?
A requirement of goods in commercial law is that they be of 'merchantable quality' under the Sale of Goods Act - which this certainly is not, and there is an implied term that this dress corresspond to the sample you tried on (or in this case your actual dress). Breach of this term results in your statutory right to repair or replace (to do so at the seller's expense) OR to rescind the contract under EC Directive 1999/44. You do NOT under any circumstances have to take faulty goods.
An oral contract may be legally binding - however, due to the above, it sounds like it's her problem. Did she make it clear her cancellation policy when you bought it over the phone? If she did send you any T&Cs AFTER making the verbal contract with you over the phone then any of these requiring you to pay the full amount if cancelling would be null and void, as you simply can't introduce new terms to a contract after making the contract.
I'm afraid my contract is a little rusty - but I just took a commercial exam on Thursday - on buyer's remedies actually! Further I would ask your Professor for some adviceBest of luck!!
I am so upset about this, I honestly thought that if I could get it in a flight bag, then it would be okay, I now have to resign myself to the fact that I must put it in my suitcase, I am so worried that my suitcase may get lost. I know it's unlikely but because the dress is so important, I'm really worried.

I have just called the airline I am travelling with to ask about my wedding dress and they have informed me that i cannot under any circumstances carry it on the plane, regardless of how small I compact itI am so upset about this, I honestly thought that if I could get it in a flight bag, then it would be okay, I now have to resign myself to the fact that I must put it in my suitcase, I am so worried that my suitcase may get lost. I know it's unlikely but because the dress is so important, I'm really worried.
So I wouldn't mind hearing some good views from people that have taken their dress in their suitcase...![]()
My heart started to relax! Well, my brother told me he would grab it. After a few moments he finally picked the bag up around it's middle. I was like "what's going on?" He said, "There's no handles!!!" WHAT???!!!
The bag was destroyed!!!! All the handles were broken off and the side was torn!!!!!!!! OMG, MY DRESS!!!! Was all I was thinking. I immediately opened the suitecase and found the gown completely unharmed!!! ahhhhhh....thank goodness. Now to kill the airline for giving me a Heart Attack! I went into the baggage claim/damaged office and told them about the bag and that MY WEDDING GOWN was in it! AND that I had been assured that it would be more than ok under the plane! She appologized and gave me a duffle style bag big enough for me to put my wedding gown in and took my destroyed suitecase...It was part of a matched set, of course...Well, anyway, I didn't want to scare you but I wanted you to know the truth...The only reason that my gown was ok (especially seeing the state of the suitecase!) was because the suitecase had hard sides and couldn't have been damamaged. SO, make sure you have a NICE suitecase, and by nice I mean Durable, to take your gown in, if you can't carry it on. ALSO, after I got off the plane the lady asked me why they didn't put a FRAGILE sticker or tag on the suitecase...of course I didn't know they even had them, so, lesson learned! Ask them for a FRAGILE sticker and/or Tag to place on the suitecase, that way at least they have some warning that the item(s) inside is valueable to someone! Well, I really hope my scary story didn't scare you...It was meant to help and the good part is the gown was fine!!! Just make sure you don't make some of the mistakes I made...Good Luck!
I am just going to pray to the heavens above that my dress will be safe, positive attitude and all that
