Summer owns a jacket wardrobe too — the evening drop, the coastal wind and the AC arctic all demand a layer that isn’t a coat. The summer lineup: five jackets rated by weight, and the pack-along strategy for days that end cooler than they start.

The Lineup

The five: the denim jacket (the summer-evening default — the LWD’s classic companion), the unlined linen blazer (the polished tier), the light utility or chore jacket (the pocket-forward casual), the packable windbreaker (the coastal and travel specialist), and the knit cardigan-jacket hybrid (the soft option). Five weights, every summer evening covered.

The Weight Ratings

The gram economy: the packable tier (the windbreaker folding into its own pocket — the tote-resident), the medium tier (denim and chore — worn or shoulder-draped, not packed), and the structure tier (the linen blazer earning its space by upgrading the whole outfit). The pack-along decision is a weight-versus-probability calculation, made at the door.

The Styling Registers

The evening-layer pairings: denim over the white dress (the summer classic that never files for retirement), the blazer over the slip (the dinner register), the chore jacket with the tank and trouser, and the cardigan with everything linen. The shoulder drape doctrine applies to all five — summer’s layers spend half their life worn as capes.

The Strategy Notes

The practical clauses: the car-and-desk stationed layers (the two-climate infrastructure — a jacket living where the cold is), the restaurant-AC forecast (indoor dining is a jacket occasion in July), and the sunset arithmetic (outdoor evening plans + coastal geography = pack the layer, always). Summer nights were always jacket weather — the lineup just admits it.

Five weights, drape-ready, stationed where the cold lives. Summer’s jacket wardrobe was never optional — the evenings voted, and the denim jacket counts the ballots.
