How to check wearables in Decentraland before publishing?
Maybe you think it is easy, but I didn't find it fast. It is very important step before a publish. It helps to check wrongs and get approval in future.
When you add a wearable, you can see a button "See in world".
After clicking, you will have a mistake.
To fix the mistake, you need to change the network in a Metamask. Click on the button "Add network".
Next step, choose "Advanced" in "Settings".
End up, you should turn on "Show test networks".
Now You can use a Ropsten, don't forget to click a "Retry".
Yay! You enter in Decentraland in the network Ropsten.
In Decentralan, You should open a "Collectibles" and check the box "Test TP" in "Linked wearables".
You can see and test your item:)
