Polo Ralph Lauren's Sullivan Slim ($110) and COS's Regular Fit ($115) are five dollars apart but built on different philosophies.

Which should you buy?
The $5 gap is small enough to set aside. Buy the Polo Sullivan if you want forgiving stretch, a dialed-in named slim fit, and classic American styling that stays comfortable from day one. Spend the extra $5 on the COS if you prefer rigid, structured denim that breaks in over time and a quiet, logo-free, minimalist look. If you dislike stiff jeans out of the box, skip the COS and take the Polo.
