I genuinely really love their tights, but only the solid colours and very subtle patterns (like the black tights with a wavy sort of a pattern). I'm a short size 12/14 and the sizing works so much better than any generic supermarket sizing.
I don't generally mind children's patterns on some adult clothing either, but the way Snag does them is very different from how M&S would do adult pyjamas with Disney characters, or something.
I don't have a problem with men wearing tights either, they are just clothes after all...
But I do find the way Snag promotes a very specific fetish type culture quite gross, and not something I want to see on my social media feeds. I joined their official Facebook group at some point and at least 20% of the posters seemed to be there to share photos of themselves in very erotic poses, including lots of men. Which is cool if that's your thing, but it's not mine. They are trying to be a mainstream fashion company at the same time as being a fetish brand and that doesn't really work.
