Lycra and hybrid bicycle I just went for a 50 mile ride on my hybrid (1/3 on an unpaved trail, 2/3 on a paved trail), and I am curious regarding the outfit I'm wearing.

Is it frowned upon to wear a skin tight (road bike style) cycling clothing while riding a hybrid? Would I benefit from a more baggy outfit? What's the "traditional" hybrid outfit?
I would say that it isn't very common to see people wearing Lycra on a hybrid. However most people I see on hybrids wouldn't ride 80 km. At that distance, the right clothes can make a real difference in energy expenditure and comfort.  The people who don't wear Lycra mostly don't know the benefits or feel too self-conscious to wear it. I think that you should keep wearing Lycra if it makes you comfortable.
