about Us

8.1 | Eight.One

At 8.1 | Eight.One , we believe that comfort and style should go hand in hand — every day, every moment.

We're a Portuguese brand born from the desire to create pieces that will last you from morning to night, with a minimalist, elegant, and timeless design. We're inspired by the latest trends, but we don't follow fads—we prefer to create our own style: natural, modern, and versatile.

Our seamless pieces (without visible seams) are designed to mold smoothly to the body, providing absolute comfort without compromising aesthetics. They're ideal for at home, going out, or even a casual date—because when you feel good, everything flows better.

We produce with attention to detail, using high-quality, durable, and carefully selected materials . We value texture, fit, and functionality—because each piece must make sense, both on the body and in the rhythm of real life.

We do what we do because we know that dressing goes far beyond clothes. It's an extension of who we are, the way we move, the lightness with which we want to live.

8.1 is for those seeking simplicity with sophistication, comfort with authenticity. For those who want to dress with purpose and lightness, effortlessly—but always with identity.

Of course. The first step is to consult our Size Guide . We also recommend carefully reading the description of the product you wish to purchase, as it may contain information about fabric compression or the cut of the item.
If you still have questions, please email us at support@oitoum.pt and indicate the models you're considering. Please mention that you've read this FAQ—that's where we always start!

At Oito.Um, we value exclusivity. We produce collections in limited quantities so that each customer feels unique. Therefore, once an item sells out, it's unlikely to be available again.
To not miss future opportunities, we recommend that you subscribe to our newsletter.
