The Dress is amazing. The details are peak and it's the best dress I got so far. All ribbons can be deattached and have cute details that fit the dress. I definitely recommend getting it with the choker, since it has many details fitting for the dress and it looks really nice together.
Since the dress looked a little "flat" or straight around the Breastarea, I ordered it in 3 XL. Just to be sure. Luckily it's fitting.
For anyone with a bigger chest, I would recommend to size up a little. Overall it's the princess dress of my dreams and it looks exactly, maybe even better, then the pictures.
For size comparison I am mostly wearing European L and I am 170cm tall. Lengthwise it was fine as well. Shorter than the pictures, but still around midi. Just be careful, anyone above 170cm may have to lengthen the shoulder straps.
