We have been looking at very nice Elizabeth Swann costume from Woolworths online and ebay. I have no clue how your sizes run. We are thinking we would need a 7-11 in UK. My DD6 wears a 7-8 US. We would like it to be a little big so it still fits next summer when we cruise. If anyone can help that would be great. Also does anyone know if Woolworths ships to the US?
