FAQS

(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.

Inquiry Type

We do everything we can to minimize the environmental impact.

Since 2021, as part of our commitment to always improve our company standpoint on the ecological aspect and find ways to be greener, we chose to ban single-use product packaging of our brand. That means our underwear don't have any extra boxes or any type of branded packaging.

As a company, we truly have to rethink how we pack and ship products. We preferred to focus the product itself to wow the clients instead of a beautiful however non essential one-time outside branded box/bag.

We decided to go foward with this because we know these types of packaging are made for visual branding and aesthetical purposes only and are pretty much thrown away directly after being opened.

To safely and carefully pack our product we only use sturdy recycled mailers that are padded with recycled fibers - We use the one shown in the picture above.

Also, all communication including customer's invoices is paperless and made through emails.

BY LANGLOIS is quality you can love and trust.

THE BRAND

We asked Vincent Langlois, 36 — founder and creative director of BY LANGLOIS — to talk about who he is, what drives him, and the new era of the brand.

(q)Why did you start a men’s underwear brand?(q)

Since I remember, I’ve always been obsessed with underwear. When I was around 17-18 and started having a bit of my own money, it became the thing I loved buying the most. (photo)

I still remember working at the grocery store, and during my lunch break I’d walk to L’Aubainerie to buy micro briefs because they were the only place selling them. The cut wasn’t perfect, but they were affordable, maybe ten dollars a pair, and I loved them. I wasn’t “collecting” underwear, but I was definitely buying a lot — it was my thing.

Early BY LANGLOIS pieces from 2020–2021 — where Vincent’s vision first took shape.

(quote)"Everything was either too expensive, not well-cut, never with unique colors"(quote)
When I wanted unique, cooler shades, the only brands offering them were insanely priced — 30, 40 dollars for one pair — and even then, the quality didn’t always match.(photo)

BY LANGLOIS’ early warehouse at the end of 2021, when the brand first started to take off.

And I’ve always had a specific aesthetic: I love monochrome, I love color, but I don’t like loud mix-and-match designs. No brand had the exact mix of what I wanted: the perfect cut, a price that makes sense, and clean monochrome colors in unique tones.(photo)

So when I finally reached a point in my life where I had enough money to invest in something real, and enough experience to build my own vision, that’s when I decided to create BY LANGLOIS — the brand I always wished existed when I was younger.

(q)People know you online through BY LANGLOIS — but who are you behind it all?(q)

I’m a small-town guy. I grew up in Granby, but I was born in Saskatchewan — my dad was in the Canadian Forces back then.
Both my parents are from Gaspésie, so I’ve got that mix of roots and energy that’s hard to shake.
I’ve always been artistic. When I was seven, I made a little “how to draw” booklet and sold it to my cousins. (laughs)(photo)

That mix of creativity and entrepreneurship has always been in me.
I studied marketing in Jonquière, in the advertising program — but I had so much drive to live and create that I left before finishing.
At 19, I left everything and moved to Montreal with only $300 to completely restart my life.

Publications featuring Vincent — known as “Vin Los” in the 2010s, his nickname during his early modeling years.

I worked in a grocery store for ten years, and during that time, I kept painting, taking photos, and creating nonstop.

In 2014, I was featured in Le Journal de Montréal, VICE Magazine, and several other publications — that’s what really opened the doors for me.
From there, I started working on creative projects in New York and beyond.

All of that eventually led to founding BY LANGLOIS six years ago.

Vincent Langlois is the founder and face behind BY LANGLOIS.

Balancing design, accessibility, and passion, he’s redefining what modern essentials look and feel like.

What he’s building goes beyond underwear — it’s a vision, a culture, a living universe.
