Just got this game a little while ago. I even got a prime and secondary gradient. However, I can not figure out how to put them on my character. Can someone please tell me how?

Go to the market on the forums.
On the left side of the screen, you see a bunch of links.
Click on the deactivated link.
You will see your gradients, and also an activate button. Press that.
You are now wearing your gradients.

Go here

Then scroll down to what you brought and click activate.

There's no only gradients, also you keep there all your items!

Go to the shop and you should see the deactivated tab. Click on it and click activate on the items you want to activate.

Ok, Thanks

buy it on shop > go to your deactive > active it > play TB

Okay. Question answered. Closing thread before people keep posting what has already been stated.
