One Nation Paris Outlet Big Sale: Dates, Deals, and Practical Information
From August 29 to September 6, 2026, One Nation Paris Outlet in Les Clayes-sous-Bois is holding its highly anticipated Big Sale. For nine days, shoppers can enjoy exceptional discounts on ready-to-wear fashion, outdoor sports gear, and home equipment, in addition to the usual outlet prices. This guide provides all the essential information to make the most of this event.
What to Expect at the Big Sale?
Inspired by the famous Lille Braderie, this outlet sale transforms One Nation Paris into a bargain hunter’s paradise. Located at 1 Av. du Président John Fitzgerald Kennedy in Les Clayes-sous-Bois, the event offers a unique opportunity to find discounted items across various categories. The sale is a nod to the northern French origins of the center’s owners, bringing a festive and communal atmosphere to the Yvelines region.
Gastronomy with a Northern Twist
To enhance the shopping experience, the center’s restaurants will feature Northern French specialties. Visitors can savor dishes like moules-frites (mussels and fries) and Maroilles cheese burgers, echoing the culinary traditions of the Lille Braderie. This adds a delightful gastronomic dimension to the event, allowing attendees to enjoy hearty meals in a convivial setting.
Family Fun and Special Guests
The Big Sale is also designed with families in mind, offering free entertainment for children on specific days: August 29, August 30, September 5, and September 6. These activities include face painting and balloon sculpting, ensuring fun for the younger visitors. To participate, children need to collect a bracelet from the Welcome & Services Desk.
A special highlight will be on Saturday, August 29, in the afternoon, when two representatives from the Miss Île-de-France competition will be present. Julia Magalini, Miss Yvelines 2026, and Elijah Oyegnin, 2nd runner-up for Miss Yvelines 2026, will meet the public, offering a unique opportunity to interact with these local ambassadors.
Admission and Pricing
Access to the One Nation Paris Outlet Big Sale is free. The children’s entertainment (face painting and balloon sculpting) is also free, provided a bracelet is collected from the Welcome & Services Desk. Discounts on items are applied directly by the participating brands.
