(Q)What makes BY LANGLOIS underwear different?
(A)Every cut we create is developed entirely in-house — refined, tested, and adjusted down to the millimeter. Our goal has always been to design underwear that truly fits every body type and every shape. The secret lies in the balance between our ultra-stretch fabric and the structured cut that keeps everything supported and in place. Together, they create a fit that moves naturally with you while feeling tailored to your body. On top of that, we approach color the way we approach design — with an artistic eye. Each shade is developed to feel unique.
(Q)When will your restock my size?
(A)Each drop at BY LANGLOIS is produced in limited quantities, so we don’t usually bring back the same pieces. Every collection is made to feel unique. Right now, we aim for two main drops a year, and we’re working toward adding more as we grow. With every release, we expand the inventory in each size as the brand continues to grow quickly, so everyone gets a better chance to grab their fit when the next drop lands.
(Q)What are BY LANGLOIS's payments options?
(A)Visa, MasterCard, Apple Pay, Google Pay, Shop Pay, PayPal, American Express, Discover, Diners Club.
(Q)What’s the fabric?
(A)Our fabric is 95% cotton and 5% elastane for stretch. The cotton we use is our signature super-soft type — breathable, long-lasting, and made to feel good every day.
(Q)How to find my size?
(A)Finding your size at BY LANGLOIS is simple. Just use our interactive Size Calculator in the Size Guide — it’s quick, intuitive, and gives you an accurate fit recommendation in seconds. Since we’ve been perfecting our cuts for years and have helped thousands of customers find their fit, we were able to build a sizing system that’s remarkably precise. You can also check our detailed Size Chart if you prefer — both tools are available on our collection and product pages.
(Q)Do they shrink or fade?
(A)No. Wash cold, hang dry, and they’ll keep their color and fit wash after wash.
(Q)Can I change my address or cancel my order?
(A)Yes — but contact us as soon as possible after placing your order. Once an order is shipped, we can’t modify or cancel it.
(Q)How do I return or exchange my BY LANGLOIS order?
(A)You have 10 days from delivery to exchange or return unworn, unwashed items. Contact us first at assistance@bylanglois.com to start the process — once we receive the return, we’ll issue your refund promptly.
For questions about your order or any general inquiries, we'd like to hear from you.
