There was a time when "gay" meant happy (and I mean just happy, just to be clear, I'm not saying that anyone who is gay is not happy - just wanted to make sure we're on the same page, no pun intended). In this case we have a designer who feeds into the image of what people think of men who make clothes (for women) and has quite some success with it.
Of course as with every movie problems and issues will arise (again no pun intended). For a movie as sexually charged as this, there is no nudity, other than people in underwear. But the main focus lies in exploiting those charged situations and the very flawed main character, by making fun of them. Not everything is a hit and especially the "violence" in it seems rather wrong than funny. There is more psychological abuse than physical of course, but the movie misses opportunities to be genuinely funny. Still it has its moments and if you like light entertainment, you could do worse
