I'm so cool, confident, and good looking, I just buy whatever Costco has in my size. It's ranged from Calvin Klein to Lucky Brand, Perry Ellis, some I can't remember, and even their own Kirkland brand. I look good in all of them. That said, the Levi's I've bought there in recent years don't feel and/or fit right. They slide off my arse or waist or something. So I avoid them now.
Costco usually has some option that is a pretty darn good deal so you won't feel like an arse if you buy them and don't like them. Then again, they'll take them back even if you wash and wear them so what's the worry?
If you're looking for fruity skinny hipster jeans I haven't come across that sort of thing there. But if your intent is too look like a grown man who has a job but isn't a dork, most of what they carry is gtg.
Buy a pair in your size, wash them, wear them, and if you like them and want more or in a different colour you better get your arse back there and buy more. Chances are in a week they won't have that style or brand any more and you'll be SOL. Unless you're really tall and abnormally thin, or very overweight. They always have waaaay too many in ecto and endomorph sizes. And run out quickly in mesomorph sizes.
I'm sure you could pay more and get something better if you shopped around, but I've never felt the need. I'm not particularly cheap, but spending $16-25 on jeans at Costco instead of the alternatives I've seen makes sense to me since they look and fit well anyway.
Hope this helps.
