Dear, friends, because the product label has made some changes, so your previous purchase of the M/L/XL size corresponding to the new label may be the S/M/L size, just a different label, the actual size is exactly the same as before. If there are other problems, you can always contact customer service to negotiate, thank you for your understanding, wish you peace and happiness.
We guarantee that the size of the product you receive and the size of the order has been exactly the same, only the outer packaging labels are different, thank you for your understanding ~!
