The capsule
- Lightweight cotton or linen midi dress — ISPRA Naples logs 30°C / 86°F afternoons through July with 65% humidity. Cotton in ivory, sand, or Capri-blue handles the daily Spaccanapoli walk; linen in oat for the George Restaurant (Vomero, Grand Hotel Parker's, 1-Michelin) sunset. Pack three — sweat saturates one in 30°C / 86°F + 65% humidity within hours, rotate two to dry.
- Linen wide-leg trousers + cotton tee or sleeveless blouse — Daily wear at the Naples Cathedral, Cappella Sansevero, Naples Archaeological Museum, the Pompeii + Herculaneum archaeological sites. Linen in flax for the Mimì alla Ferrovia lunch; cotton tee + tailored trousers reads correct everywhere. Skip black entirely — heat-absorbing in 30°C / 86°F + Vesuvius volcanic dust shows on dark fabric.
- Comfortable closed-toe leather sneakers or Capri-leather sandals — Naples Centro Storico walking unchanged from June — uneven cobblestones throughout Spaccanapoli, hill climbs to Vomero, the Pompeii + Herculaneum archaeological sites add 5-7km of dirt + ancient-stone trails. Leather sneakers from Common Projects, Veja, or Bottega Veneta in cognac or white; Capri-leather sandals (Canfora founded 1946 + Da Costanzo in Capri Town, $150-300 hand-stitched made-to-measure on the spot) for evening + the Capri day.
- Light cardigan or cashmere shell — ISPRA logs 21°C / 70°F overnight lows through July. The Mediterranean evening cool drops to 23°C / 73°F by 21:00 even on 30°C / 86°F afternoon days; the Riviera di Chiaia + Lungomare Caracciolo seafront catches Tyrrhenian breeze. Cotton or merino in ivory, navy, or Capri-blue layers under the linen midi for the Caffè Gambrinus evening espresso and the Capri Quisi-Bar terrace cocktail.
- Packable rain shell — ISPRA logs 2 rain days through July (the driest month) but Mediterranean afternoon thunderstorms still possible. Pack a 2-3oz Marmot or Patagonia Houdini in the crossbody; skip umbrellas — Tyrrhenian wind defeats them and narrow Spaccanapoli alleys make them a walking hazard.

Leather crossbody from Bottega Veneta, Furla, Coccinelle, or local Neapolitan leather workshops in Spaccanapoli. Polarized sunglasses cut Tyrrhenian glare on the Lungomare Caracciolo and the Capri Faraglioni boat-tour; SPF 30 mineral preferred (Stream2Sea, Sun Bum Mineral) for the Capri snorkel + the open archaeological sites; wide-brim sun hat (4-inch brim minimum) for Pompeii + Herculaneum + Capri (no shade, full-sun midday).
