Mens Hosiery and Pantyhose

Pushing the alliteration envelope right there, but that is, as they say 'all good'. I've expressed this sentiment before, but I don't think that it can really hurt to express it again: men look great in stockings.
Because men tend to carry their weight differently from women i.e, in their bellies rather than their ass, thighs and abdomen, they tend to have great legs. This applies especially to men on the taller side, but almost any man looks great in a pair of tights, stockings or pantyhose.
That's probably why men wore them for so long, prancing about the world in just a pair of hose and a jerkin. Try dressing like that now and you'll get more than a few strange looks. Unless you're a ballet dancer of course, those guys get to manhandle women whilst dressed in lingerie all the time.
If you're over the age of about 10 (which you better be), then you can probably forget the whole ballet dancer thing. It takes years of torturous training to become one, and all things considered, its probably not worth dedicating your entire life to dance just to get away with wearing stockings in front of hundreds of adoring fans. With Al Gore's invention of the Internet there are plenty of opportunities to do that on web cam without having to have any special skills.
But Will It Fit?
Most men shouldn't have too much trouble finding hosiery to fit. Pantyhose could be a problem if you have especially long legs. Even women have problems with the dreaded 'hose gap' which appears between the crotch of the wearer and the crotch of the garment, creating a strange air filled void which traps sweat like the lingerie black hole it is. If in doubt, buy the next size up, if there is no next size up stockings will work well in the place of pantyhose and come with the added perks and frills of wearing a garter belt. (Assuming you don't buy stay ups. Men can often wear stay up stockings better than women because of the greater muscle mass in their legs creating less 'stocking bulge' which often occurs when a lady wearing stay ups has, shall we say, amply endowed thighs.
In winter, tights can be a welcome addition to everyone's wardrobe. You might even be able to get away with calling your tights 'thermal underwear'. Or, if you're super in the closet about wearing hosiery, you could wear thermal underwear and pretend that you're actually wearing a pair of tights. Then you could feel a little silly about lying to yourself like that and just put on a real pair of stockings.
The Final Word:
Long answer short: Yes, men can wear tights Or stockings. Or pantyhose. Or whatever else takes their fancy.
