Costume National Sea Thru 100ml EDP

Sea Thru by CoSTUME NATIONAL is a luminous unisex Eau de Parfum launched in 2024, designed to evoke the clarity of sunlit sea water and a breeze that feels instantly fresh. Crafted by renowned perfumers, this fragrance blends bright citrus with a clean marine heart and a quiet, mossy-amber drydown. Housed in a turquoise-tinted bottle that echoes coastal light, Sea Thru is built for everyday wear, from sunlit city mornings to relaxed weekends by the water. It sits comfortably at the intersection of aromatic fougere and aquatic tones, offering transparency without sacrificing presence throughout the day.

Fragrance notes

• Top notes: Bitter Orange, Lemon, Grapefruit



• Heart (middle) notes: Sea Notes (marine/saltwater accord), Cypress, Neroli

Sea Thru opens with a crisp citrus ensemble that feels instantly fresh, then reveals a distinctive marine heart accented by cypress and neroli. The drydown grounds the fragrance with green moss and ambered warmth, creating a balanced, breathable sillage that lingers without overpowering. The inclusion of a marine saltiness and subtle modern notes gives Sea Thru a contemporary glow that sets it apart from traditional maritime scents.
