Frequently Asked Questions

Need more info? We’ve got you covered.

Is your underwear GOTS certified?

All of our underwear is GOTS certified, with the exception of our plant-dyed styles. While these are made using GOTS-certified organic cotton, we currently work with a dye house that is not yet GOTS certified. We’re actively working toward full certification across these styles as well.

Is your underwear plastic free?

Some of our underwear styles are plastic free. View our plastic free collection here. Please note these styles are not suitable for those with latex allergies.

How do I find the perfect size?

We've added a size guide to every product page in order to assist in helping you find the perfect fit! This guide can be found right above the quantity box, or where you would select the number of items you wish to purchase.

Alternatively, please feel free to reach out to us at hello@qforquinn.com if we can answer any questions or offer any additional sizing guidance.

What should I do if I’m between sizes?

If you’re in between sizes, choose the larger size for a more relaxed, comfortable fit. If you prefer a more snug feel, you can size down, but comfort is key for everyday wear.

Does underwear stretch over time?

Yes, natural fibers like organic cotton have a gentle stretch that adapts to your body. While they hold their shape well, you may notice slight softening and flexibility with wear.

How should I wash organic cotton underwear?

Wash in cold or warm water with gentle detergent and avoid bleach or fabric softeners to maintain softness.

Why choose organic underwear over regular cotton?

Unlike conventional cotton, organic cotton avoids toxic dyes and pesticides, reducing skin irritation and supporting healthier, more sustainable farming practices. To learn more about our certifications click here.

Where is your underwear made?

Our underwear is made in a family owned, GOTS certified facility in India.

Does organic cotton underwear help prevent rashes?

Yes, its breathable, chemical-free fabric helps reduce moisture buildup and irritation, which can lead to rashes.

What’s the difference between 95% organic cotton and 100% organic cotton underwear?

The main difference comes down to stretch and structure. 100% organic cotton underwear is made entirely from natural fibers, offering maximum breathability and a soft, natural feel; ideal for sensitive skin. However, it has less stretch.

95% organic cotton underwear includes a small amount of elastane, which adds stretch, flexibility, and helps the underwear maintain its fit after washing. This blend moves with your body and stays in place throughout the day. It's a great option for active underwear or styles that require a bit more stretch.

Both options are safe and comfortable.
