Confess - how many different sizes have you had in your closet at 1 time?
All the 12s I'm wearing are about 10 years old. The ones that I have that are so tiny we're bought about 3 years ago but who knows how old they are since they were a thrift store purchase. They look practically brand new but they may be 20 years old! Levi's has classic styles that don't really change much.
