I agree that men's bags or fashion in generally are lacking in style or fashion details, for example in men's section of tees, a tee is just a tee, probably with varying prints on the front but that's about it, whereas ladies' tees have different shapes, cutting, designs and stuff that are not just limited to prints, so I have always felt men's fashion are definitely boring.
Bags don't have genitals so I don't see why it can only be a ladies bag. I strongly dislike the way some people associate things with genders, i.e. pink only for ladies, blue only for men; handbags for ladies, messenger bags for men only. I mean put it the other way round, many ladies use men stuff, why can't men use ladies stuff? Makes life with so many limited options, and this I think is very stupid.
IMHO the
Coach Borough Bag is one bag that really suits fine on both ladies and men, it's such a fantastic design and shape, and neutral in every way if you look at it alone. Once it's worn on a lady it'd make the lady look very elegant; while on a man it'd look like a wonderful everyday bag / briefcase that's big enough to fit documents, MacBook Air, etc.
If people give you weird looks, screw them! Don't give a toss about them who have very narrow-minded brains and they live only inside a box set with a narrow list of strict rules of social norms that were probably derived from the 19th century. They should learn to accept others have their own tastes and preferences, and embrace life that changes everyday and moves on. Again, put it the other way, in the medieval times tights used to be men's thing, now it's ladies fasion; UGG boots initially started off as men's items (soldiers specifically speaking); same goes to riding boots until we kind of stole them to be our fashion items. The war had a lot to do with changes in fashion and stuff, but there is no reason why men can't use stuff that were originally their own, or reverse the trend like how things did in favour of ladies.
If you like it then get it!! It's such a wonderful bag! Just one advice though: don't hold it on your arm or how you wear it on your shoulder like how ladies do. See these images below and you'll see what I mean;
Get a wider strap for crossbody wearing, not as wide as the image below, that'd ruin the great appearance of the Borough, but get one about 1 inch wide. That'd look good on men.
I have absolutely no problem with men using ladies stuff, if that means making life and fashion a bit more interesting. Just make sure you know how to make yourself look good!

Thumbs up from me!
