colored jeans...

I saw an outlet store selling Zara's colored jeans from last year.  I'm kind of hesitant to buy because since it's a trend, I feel like I won't be getting my money's worth once it goes out of style. I decided to just come back.  I couldn't resist the price though..it's only 20 riyals..that cheap! So as I am typing these words, I've finally decided I'd get myself a pair... or maybe two, hehehe...

Should I buy 2 or just a pair?
