Just bought my first pair of Levis

[Tangtasic]

Probably a question I should have asked before purchase but, how long can I expect a pair of Levi's to last me?
Decided to splash out as I seem to be wearing through jeans alarmingly quickly and I thought buying from Levi's would probably get me better quality.
Until now I have been buying Mango/ H&M but finding the crotch area wears out after around 4 months. Wearing the jeans around 3 times per week.
Is it reasonable to expect the Levi's to last around 2 years?

Certainly my old ones did. But like doc Martin and every other old brand, quality has declined in recent years so I wouldn't be optimistic.

It depends.

Do your thighs rub together, is that what's causing the wear, or are they very tight? Does the denim go thin or does the stitching go?
