Six Stories Women's Scoop Neck Sleeveless Skater Mini Dress

Normally a 12, first orders a 14 as I know dress is UK sizes, they sent an 18UK which fits like a woman’s 18w or 20. Re ordered a 12 as I love it and thought with the lace I could cinch it tight, it arrived, it’s UK size 16. I am normally a 14UK, but I have to say I think the 10 would be too big also if it were available I would size down to an 8 and even then it may be too big. The sizing is way off on this dress. Size down at least 3 sizes maybe even 4! Bummer I will need to return both and there are no smaller sizes available to purchase. The dress is heavy nice quality material. I would keep it for sure if the sizing was correct.
