We're truly sorry to hear that the seam split while you were trying on the item. This is certainly not the quality or experience we want our customers to receive, especially after you've waited so long for your order to arrive.
We appreciate you bringing this to our attention, and we regret that you've had to consider repairing the item yourself.
Please contact our customer service team with your order number and a few photos of the damaged seam. We'd like to take a closer look and help find a suitable solution without putting you through any unnecessary trouble.
Thank you for your feedback. We'll also share this issue with our quality control team for further review.
