How to crop an image in Instagram (v6.4-6.5)

[zerkms]

I know it sounds silly but I spent half an hour trying to find how to crop an image taken by built-in Instagram facilities and then how to crop it right after that.

Surprisingly there is only a tool to rotate an image and no crop available anymore.

So the question is: could anyone please show me how to crop an image in the latest available (v6.4-6.5) Instagram application?
