Comparing Agolde Luna comes down to two or three measurable differences rather than a general sense of quality. Anything over about 2 per cent elastane will bag at the knee by the afternoon. Check the leg opening, not the name; two brands can call the same measurement straight and wide. Rigid denim gives about half a size after a week. Stretch denim gives it back after a wash. The groups below run from the decision that matters most to the ones you make afterwards.

What decides this is rise, leg opening and stretch content. Everything else is preference. Two from the first group show the range: whitefoxboutique.com's Just My Type Mid Rise Wide Leg Jeans Sesame Wash at $80, and nydj.com's Barbara Bootcut Jeans In Tall - Black at $99. The first is the easy entry point; the second is where the money goes. Rigid denim gives about half a size after a week. Stretch denim gives it back after a wash. Anything over about 2 per cent elastane will bag at the knee by the afternoon. A higher price mostly buys materials and finishing, and occasionally it buys nothing at all.

Rise decides everything above the waist, so pick the top second. Hem to the shoe you actually wear with them. From the second group, A.P.C.'s Rescue Jeans ($340) is the one that earns its place, because it works in more than one context without being restyled. The third group is smaller and deliberately narrower, jeans, for the decisions you make after the main one. None of this needs the whole group. One piece from each is usually enough.

There are 20 jeans here from 15 brands, $64 to $558, all in stock when this was written. We would not buy all of them, and neither should you. wildoakboutique.com's Calvin Risen Jeans at $64 is the low-risk way in, and lagarconne.com's Wobbly Cotton Jeans at $558 only makes sense if this is a category you already use constantly. Read as a set, they get you close to Agolde Luna without any single purchase being compulsory. Nothing here is included because it is famous, and price is not used as a proxy for quality anywhere on this page. If you take one thing away: pay for the thing that touches your body and economise on the thing that sits on top of it.
