I also reported a few of the more overt ones.
I find it so inappropriate, I could honestly do with some new bra's & undies but good grief am I put off by the prospect now.
If I wanted to see reviews of men wearing women's underwear/lingerie, I'd go to somewhere like Love Honey or Anne Summers, where it's expected and appropriate.
We shouldn't be seeing this from more "every day" stores like M&S.
I get they have a "lingerie" section and lingerie is arguably different from more "normal" underwear, but let's be real, they're awfully plain for "lingerie" and most if not all of M&S's underwear products you could easily wear as an "every day" item, as opposed to the types of clothing Love Honey or Ann Summers provide.
It's just not the appropriate place for that type of review.
