About the size, you can find all the details about the sizes of each item on every product page. To choose a correct size, we usually suggest that customers can measure their own size and then read the size reference on our product page, not the usual size you ordered.
We have measured the items before selling them. However, If the product you have received does not meet the size chart, please reflect it to our customer service with some measurement pictures of products to show this problem, our customer service will check it carefully and then offer you a reasonable solution according to the return-refund policy.
