Charleston in May is Lowcountry late spring. NOAA Charleston data put afternoon highs at 27°C / 81°F and overnight lows at 17°C / 63°F with 9 rain days. The dressing register is Lowcountry-Southern preppy: M Dumas & Sons (Charleston-founded 1917, the heritage Lowcountry menswear with seersucker and tropical wool tradition); RTW Charleston (contemporary Lowcountry women's); Croghan's Jewel Box (Charleston-founded 1907, the heritage Charleston jewelry); Tucker Blair (Lowcountry-popular Charleston-Atlanta); Vineyard Vines (Martha's Vineyard but ubiquitous in Charleston); Lilly Pulitzer (Palm Beach-founded but Charleston-popular). Seersucker (the puckered cotton fabric, Charleston-Savannah-Lowcountry heritage — most-cited as the 'old Southern gentleman's summer suit') is the local heritage textile. The historic district (King Street, Meeting Street, Tradd Street, the Battery, Rainbow Row, Charleston Single Houses) is cobble + brick — flat-soled leather sandals or loafers only. Spoleto Festival USA (the heritage 17-day arts festival, late May through early June, founded 1977 by Gian Carlo Menotti) brings opera, theater, dance, jazz programming.

Seersucker, linen, leather sandals — the heritage Lowcountry preppy register.
The capsule
01Lightweight cotton or linen midi dressNWS Charleston (CHS) logs 27°C / 81°F afternoons through May with humidity climbing past 70 percent. Cotton in oat or sand handles the Spoleto Festival USA opening (late May, 17-day programming founded 1977 by Gian Carlo Menotti); linen in ivory wrinkles less for a Dock Street Theatre (1736) evening.
02Linen wide-leg trousers or seersucker-cotton trousersDaily wear at Hampden Clothing (King Street since 2007 — stocking The Row, Khaite, Loewe). Linen in flax or oat for FIG (Mike Lata, 1-Michelin since 2003); seersucker in classic blue-and-white for the Charleston preppy heritage register through Cannonborough-Elliotborough creative blocks.
03Leather sandals or seersucker-cotton loafers — M Dumas & Sons (1917)M. Dumas & Sons (Charleston 1917) loafers in tan handle the French Quarter cobble that destroys heels by block three. Leather sandals in cognac for King Street brick; the Battery cobble grips uneven from the 1830s harbor wall onward — flat soles only.
04Swim + cotton cover-upFolly Beach (15 min south, 6-mile barrier-island) and Sullivan's Island (the heritage 1860s lighthouse beach) sit at 22°C / 72°F sea per NOAA. Cover-up in sand or sage for Bowens Island Restaurant (the heritage Folly Beach oyster shack) post-swim.
05Light cardiganThe Charleston Battery harbor wind drops evenings 3-4°C below midday — to 17°C / 63°F per NWS Charleston. Cotton or merino in ivory or oat layers under the seersucker shirt for FIG dinner without competing with the linen drape.
06Wide-brim sun hat + polarized sunglasses + SPF 50UV index 9 (very high) in Charleston May per NWS. Subtropical haze cuts visible glare but not UV — pack mineral SPF 50 (Supergoop, Coola).

Haspel founded 1909 in New Orleans set the cotton standard — Charleston kept the tradition.
08Crossbody bag + reusable water bottleHistoric district walking from the Battery to Marion Square covers 1.5 miles in 70-percent humidity.

Seersucker is the puckered cotton fabric — Charleston-Savannah-Lowcountry heritage textile. Most-cited as 'the old Southern gentleman's summer suit'. The puckered weave creates micro-air-gaps between fabric and skin, making seersucker the heritage humidity-friendly summer fabric. M Dumas & Sons (Charleston 1917) makes the most-cited Charleston seersucker; Brooks Brothers (1818) makes the most-cited national seersucker. Tradition: seersucker is worn between Memorial Day and Labor Day (the unofficial Southern Memorial-Labor Day rule); seersucker outside this window reads as 'fashion choice' rather than tradition. Pack: a seersucker shirt or trousers handles 25-32°C / 77-90°F humid heat well.

Yes — Folly Beach (the heritage Charleston-area beach, 30 minutes south) is the most-cited Charleston beach day-trip.
