Long before the internet was invented (by Al Gore), there were these things called books, which we used as reference sources. Check your local library or giant bookseller like Barnes & Noble. You should find more male costume pictures there than anywhere in cyberspace. I've even seen books with male costume sewing patterns, if you want to do it yourself.
If you can be more specific as to what you're looking for, perhaps I can give you specific book names or websites that might have exactly what you need. Good luck.[/i]
