gollob,
Life isnt a function all the time, and smart dress is for the proper occasion/s and If people want to wear jeans ( smart/designer, holey, ripped, or manky with paint on them )...why the hell not?
I like seeing women in jeans, as they look just so marvellllloussss!.
Suggest you smarten up on your manners.
No offence meant, of course. :0)
