Underwear Models

No idea but Charlie underwear (the 1st pic) hasn't used many models, so maybe Google?
And I can’t see the name (fragrance?) of the bottle (the 2nd pic). Maybe you can do a Google search on both.
Here’s a tip: attachments look blurry at first glance but if you click on them the full quality image pops up. The fragrance is also Matthew Zink, part of the same Charlie campaign.

I wasn’t able to find who the model was though, they made a bunch of posts with the same guy but you don’t see his face and they never tagged him.
