I like nothing better than to pull on some comfortable blue jeans. What are the best blue jeans I can buy?
It sounds like you really like blue jeans!  I suppose it would depend on whether you are looking into men's or women's blue jeans.
Definitely men's jeans. What are the most popular, but affordable men's jeans?
I've heard that Blank NYC has a ton of well fitting styles and they have many sales as well as heavy trickle down to mid range stores like TJ Maxx and Marshall's.
What price range are we talking about?  I don't really want to spend a fortune on blue jeans.
Then, Maybe you should try Old Navy?  I think BlankNYC can be purchased in the 65-95 dollar range, American.
65 isn't too bad. 95 is getting up there. What would be the range for Old Navy?
I really wouldn't know.  45-65? How long have you been interested in Men's fashion?
I'm primarily interested in casual men's fashion.  
I see, what are your favorite casual men's brands and why?
I like Levi, Lee's.  L.L. Bean. Comfortable cloths. What other brands fit in that catagory?
