I love the crown. Personal preference, it could be a bit taller, like 1-1.5 cm taller.
Aside from that, I like the material being flexible enough to change it slightly if needed through pressing on the sides. My only big critique is the hairpin holders. Not everyone has long hair so having metal hairpin rings actually shrunk the interior. Once I popped those off with a pair of pliers, it fit like expected.
I bought this crown a year ago. It fits great and the quality is superb. It has held up well. I highly recommend it.
