Are you on vacation on the French Riviera?
Mid-August is also peak tourist season: if you're staying in Cannes, Golfe-Juan, Antibes, or Nice for the summer and obviously haven't packed a costume in your suitcase, don't panic. Our two stores are open 6 days a week until the last minute, and a good portion of our August clientele consists precisely of vacationers who come to complete their look just before the ball.
What costume for the Shellfish & Crustacean Ball?
For her: the mermaid
The quintessential classic for this theme. Three mermaid wig styles are available depending on the desired ambiance: enchanting green mermaid wig, mermaid wig adorned with pearls for a more glamorous look, or red mermaid wig with starfish for a bolder style. Complete with the mermaid makeup kit with stencils and glitter and the white flower pearl necklace.
For him: the captain
Head to the helm with the Cruise Ship Captain costume (jacket, cap, and trousers). Easy to wear all evening, it remains comfortable even in the heat of August.
As a duo: sailor & mariner girl
For those who prefer to coordinate their looks as a pair, the Mariner Girl costume (belt, hat, and dress) pairs perfectly with the Captain costume. Want to stray a bit from the literal theme? The Women's Pirate costume (hat and dress) stays within the maritime spirit while adding a more unconventional touch.
Reserve online, pick up in store
During peak season, some items (especially M sizes of the Cruise Ship Captain and Mariner Girl) sell out quickly. The safest option is to order online and pick up via free Click & Collect in Mougins or Villeneuve-Loubet, or call the store for a reservation.
