I ordered a 3X, because that's the size that the website said to order, it came and lacked about 8 inches closing....so I looked at the package and it says I should have ordered a 5x...seemed extreme, but I exchanged it.

I was very impressed with the speed of the exchange, I'll say that....

However, when the 5X arrived, it's so big it just gaps and falls off?  So, was the 3X mislabeled, or is this 5x mislabeled?  I'm needing something with some firm support for post surgery care....so I really don't know what to do at this point?
