Carol, my clientele run the gamut with how much they spend on jeans. There is everything from $10 at goodwill and $40 at Old Navy, to $1500 for a designer brand - plus everything in-between!
Some clients do VERY well with fit and quality from Old Navy, Gap, Wit & Wisdom, Jag, Lane Bryant, KUT, Eloqui, Zara, Loft, Mango, M&S, and the like. Others have stellar luck at J.Crew, NYDJs, Boden, Pilcro, Madewell, Levi's, Everlane, G-Star, COS, Massimo Dutti, and the like.
Then there are the premium brands that cost in the hundreds of dollars like Paige, Rag 'n Bone, Mother, Frame, AG, Citizens of Humanity, Joes, to name but a few. Designers like Veronica Beard, Polo by Ralph Lauren, Hugo Boss, GANNI, Cinq a Sept, Essential Antwerp, and Elie Tahari make jeans, and they are in the same premium price points.
And if you want a pair of jeans from Gucci, Versace, Chanel, Isabel Marant, and the like - you will pay top dollar.
Personally, I'm nodding along with Janet and Suz. Like Suz, my style is "trendy on the bottom" and more classic up top. I am an early adopter of jeans trends, and wear fringe trend jeans (and pants). That's part of what makes fashion fun for me! Premium denim brands tend to make fringe trend styles first, and that's why a larger portion of my capsule is premium. (Although Zara makes fringe trend jeans first too). I live in a climate wear I can wear jeans for most of the year. It's money well spent. Also, white jeans are my thing! Dressy jeans can be worn to work with clients. I will pay premium price for polished, fab fitting, good quality, on trend jeans.
Here is my current jeans capsule. You'll see premium brands, AND non-premium brands:
