Originally purchased from the Japanese website 'Bodyline' in 2018. In very good condition as only worn a couple of times. It's very nice quality unlike most of the cheap costumes you can buy here in the UK. It's a Japanese size M which is more of a UK XS/S. It fits me fine as a size 6 since the apron can be tied as tight as you want but would also fit a size 8, probably a 10 too. Fastens with zip at the back. The apron ties at the back and the black bow attaches to the front of the dress with a safety pin. The arms are elasticated to give a cute puff sleeve effect. I cut the apron straps because they were ridiculously long and didn't actually sit properly won in a cross on the back and have safety pinned them so they can be adjusted (I didn't sew them in place in case I wanted to shorten them further in future). The measurements are as follows:

Armpit to armpit: 18 inches
Waist laid flat: 14.5 inches
Length of trousers: 32 inches

Included items: Blue dress. White apron. Black pin on bow. Blue bow headband. 

Please note the photo of the box was taken years ago when the outfit first arrived and I no longer have this and have stored the outfit in a plastic bag in my dress up drawer. I've included the photo since it shows nicely how the outfit looks worn. Sadly even though I've worn it twice I didn't get any photos either time to show how it looks on :(
