Women's Organic Cotton T-Shirts
We’ve always believed basics should feel anything but basic. Yet, the perfect t-shirt is surprisingly hard to find.
At Not Basics, we design naturally breathable Organic Cotton t-shirts for those who are tired of thin, synthetic basics that lose their shape, trap heat and never quite feel comfortable against the skin. Crafted from 95% Organic Cotton with 5% elastane (for stretch and recovery!) our t-shirts let your skin breathe and are designed to last.
Unlike many flimsy or see-through t-shirts, our bestselling fitted styles are double-lined – so they aren't see-through. We also offer relaxed-fit t-shirts crafted from a heavyweight interlock Organic Cotton fabric - perfect for those who love the idea of oversized t-shirts, but hate the reality.
Choose from a range of bestselling silhouettes including short sleeve t-shirts, long sleeve t-shirts, cropped t-shirts and a range of versatile colours from sizes XS–3XL.
Not sure where to start? You can't go wrong with a crisp, white relaxed fit t-shirt.
What makes these Organic Cotton T-Shirts 'Not Basic'?
Our Organic Cotton t-shirts are thoughtfully designed to solve three common frustrations with everyday basics:
1. No sheer here
Our fitted organic cotton t-shirts are double-lined for a non-sheer finish, so you can wear them with confidence without worrying about them being see-through.
2. Naturally breathable
Made from 95% Organic Cotton, our t-shirts allow your skin to breathe and feel comfortable throughout the day. Unlike many polyester-heavy basics, they won't leave you feeling hot, sticky or uncomfortable after hours of wear.
3. Designed to last
From the quality of the fabric to the construction of each garment, our t-shirts are made to hold their shape and become wardrobe staples you'll reach for again and again.
Crafted from buttery-soft Organic Cotton, our t-shirts feel gentle against the skin while remaining durable enough for everyday wear.
Are your Organic Cotton t-shirts see-through?
No – our fitted organic cotton t-shirts are double-lined to create a smooth, supportive and non-sheer finish, so you can wear them with confidence throughout the day.
Our relaxed fit t-shirts – perfect for those who love the idea of oversized but hate the reality – are made from a high denier interlock fabric that isn't see-through, even in white.
Unlike many thin, flimsy t-shirts, our Organic Cotton styles are designed to provide better coverage while remaining naturally breathable, comfortable and soft against the skin.
What's the difference between Organic Cotton and polyester t-shirts?
The biggest difference between Organic Cotton and polyester t-shirts is the fabric itself. Organic Cotton is a natural fibre, while polyester is a plastic-based, synthetic material.
Organic Cotton t-shirts are often chosen for their softness, breathability and comfort. The natural fibres allow air to circulate more freely, helping regulate body temperature and keeping you comfortable throughout the day. Many people also find Organic Cotton feels gentler against the skin, particularly when worn for long periods.
In contrast, many people find polyester-heavy t-shirts feel less breathable than natural fibres, making it harder to stay cool and comfortable throughout the day. Synthetic fabrics like polyester can also be more prone to amplifying and retaining odours over time.
At Not Basics, we choose Organic Cotton because we believe everyday basics should prioritise comfort, breathability and longevity. Our Organic Cotton t-shirts are designed to feel soft against the skin, hold their shape wear after wear, and become the pieces you reach for most often in your wardrobe.
How do I care for my organic cotton t-shirts?
We recommend washing your organic cotton t-shirts with similar colours at 30°C and lying flat to dry. Avoid tumble drying to keep the durability and shape of your tank tops.
Where are your organic cotton t-shirts made?
All Not Basics tank tops are made by our trusted manufacturing partner in Istanbul, Turkey.
Our manufacturing partner is both SEDEX audited, meaning they meet internationally recognised standards for responsible manufacturing, and GOTS Certified.
GOTS is the worldwide leading certification for textiles made from organic fibers – but beyond that, the certification mandates strict International Labour Organization (ILO) standards, guaranteeing fair living wages, no forced or child labour & safe working conditions.
