Hi Naoko! Thanks so much for your feedback and we are sorry to hear the corsage didn't meet your expectations. They are intended to be one size fits all with the stretchable band for bigger wrists, but totally understand that it may not have been an ideal for a 7 year old!! Sorry that wasn't communicated better.
To improve in the future, we'd love it if you have any pictures you could email to hello@thefernseed.com -- we don't remember what flowers were used in this, but it may be that we chose a flower that wasn't able to hold up out of water and that would be great for us to know!
We hope the other florals you ordered were looking good and that you were satisfied with the design. Please let us know if there were any other issues!
