About Authentic Version and Replica Version The top quality of the authentic/replica version may look the same, but there are many differences in the details. They have different fabrics, manufacturing processes, versions, structures, and prices.

If you decide to buy an authentic version, we recommend choosing one or two sizes larger than your usual clothing size. For more details, pls check this:
