LOL, love how the dad/beefy fetishists are outing themselves.
If we're going to talk body positivity in the men's fashion sector, just know they won't necessarily go for the daddies. Or rather, they shouldn't. As proven in this thread alone the dad bods are still considered the norm. Not in fashion but in general pop culture.
The ones they should be shoving in everyone's faces are the Jonah Hill and James Corden types. These are the type of guys who bear the most brunt from the media and public scrutiny in general.
As for the campaign, I actually like the burst of yellow, but I'm so numbed by these sort of tanned and toned bodies. I see it every month in Attitude so nothing really novel about it. In fact it's the back cover ad of the current issue of Attitude.
