FAQ

What is Oui Oui & Co?

Oui Oui & Co is a Portuguese fashion brand focused on meaningful words and everyday essentials. We create timeless pieces designed to be worn often, thoughtfully made and produced with intention.

Where are your products made?

Our products are made on demand by trusted production partners. Blank garments are responsibly sourced, and each piece is produced only after you place an order to avoid overproduction.

Why is on-demand production important?

Producing on demand allows us to reduce waste and unnecessary stock. It’s a more conscious approach to fashion — fewer resources, less excess, and more intention behind every piece.

What materials do you use?

We prioritize responsible materials such as organic cotton and recycled fibers. Each product page includes detailed information about fabric composition and certifications.

Are your products sustainable?

We believe sustainability is about thoughtful choices, not perfection. Our focus is on:

Responsible materials
On-demand production
Quality pieces designed to last

We’re committed to continuous improvement and transparency.

How do I choose the right size?

Sizing details are available on each product page. Please note that some items follow European sizing and may run larger — when in doubt, we recommend checking the Size Guide or sizing down.

How long does shipping take?

Because our products are made especially for you, production takes a little longer than mass-produced items. Once your order is ready, shipping times depend on your location. You’ll receive tracking information as soon as your order is on its way.

Do you ship internationally?

Yes, we ship internationally. Shipping costs and delivery times are calculated at checkout based on your location.

Can I return or exchange my order?

As each item is made on demand, we only accept returns or exchanges in case of defects or production errors. If there’s any issue with your order, please contact us — we’re here to help.

How should I care for my pieces?

To keep your Oui Oui & Co items looking their best, we recommend following the care instructions provided on the product page and label. Proper care helps extend the life of your garments.
