Hello! Isn’t this your collection, too? You can add another avatar’s representation without making new collection or even adding completely new item for it, just find the “Add male\female representation” in builder.
As of the male T-shirt in this collection - it’s almost good to go, but there seem to be a slight rigging issue here:
Also, please, give feedback concerning your second collection, mentioned above. There might have been a problem with approval.
Cheers!
