Union Jack Dress

I want to buy a Union Jack dress for a skit I attend in a few weeks. I looked online, and many stores are sold out their supplies! These sites are British and I do not even know the size comparison between theirs and ours here in the United States. Are there any U.S. stores or websites that can lead me to find one for me? Thank you!

Good luck!

I just looked on eBay and there were lots of Union Jack dresses sold. I would say eBay is your best bet. Good luck!
