To help you better choose your size, on each product page we offer you a size guide with the body measurements (chest, waist and hip) that correspond to each size so you can measure yourself and choose the one that best suits your figure.

We also provide the equivalence of size between countries, as well as the height and size of the garment worn by the models in the photographs so you can get an idea of the style and size of each garment.

If you have any questions about your size, please write to us at shop@thinkingu.comFewer returns equals a smaller carbon footprint!

The production of materials generates most of the fashion industry's carbon footprint. For this reason, we choose materials with the lowest environmental impact, from nature and even from waste, to create garments that do not put our resources and those of future generations at risk.

In Thinking Mu we use the transparency and traceability tool BCOME in all our collections, with which, with a simple 'click', you can get data on the impact on the planet and people that has generated the production of each of our garments.

The materials we use are:

• Organic cotton: it is grown in fields of fertile and living soil, without pesticides, herbicides, synthetic fertilizers and is spun and processed without chemicals.
  The cultivation respects the cycles of the soil, preserving and promoting its fertility for future uses and consumes 91% less water than conventional cotton cultivation. And the cotton is always non-genetically modified.
  The absence of toxic residues in the cotton also makes the garment softer, more resistant and breathable, and reduces the possibility of allergic reactions.
  100% of the cotton used in our garments is organic or recycled. And 100% of the organic cotton is GOTS (Global Organic Textile Standard) or OCS (Organic Content Standard) certified.
• Recycled or regenerated cotton: one of the most sustainable and respectful materials in all its processes, resulting from the conversion of cotton fabric into fibers that can be reused in new textile products.
  It can be obtained from the remains of clothing manufacturing (post-industrial origin) or already used garments (post-consumer origin). All our recycled cotton is post-consumer and GRS (Global Recycled Standard) certified .
• Hemp: Hemp is a 100% vegetable fabric of organic origin. In addition, this plant grows very fast and all of it is used, so there is no waste. No chemicals are used in its cultivation and it leaves the soil in very good conditions for the following crops.
• Tencel: a state-of-the-art natural fiber obtained from wood pulp, mostly from eucalyptus but also from pine, beech or fir. The result is a very soft fabric that regulates body temperature, is highly resilient and absorbent.
  All our tencel is from Lenzing Group, recognized by the international environmental non-profit organization CDP for its transparency and performance in the areas of climate, forest and water safety and has been included in the annual "A List". Lenzing is one of twelve companies worldwide rated with an outstanding "AAA" rating.
  Lenzing sources wood and pulp for dissolving from sustainably managed forests and plantations and not from old, protected or threatened forests. Lenzing's biorefinery process ensures that 100 percent of the wood components are used to produce soluble pulp for the production of fiber, biorefinery products and bioenergy.
  All of its fibers are compostable and biodegradable in soil and water.
• Refibra: a revolutionary textile solution made from discarded cotton fabrics and responsibly harvested wood pulp. This regenerated cellulose fiber is also from Lenzing Group.
• Ecovero: It is produced from wood pulp from ecologically protected, specially processed forests that is used to make soft, silky fabrics. This biodegradable fiber is also from Lenzing Group.
• Post-consumer recycled polyester: produced from plastic waste collected from the environment, mainly from the sea and landfills, thus contributing to a lower environmental impact in its manufacture.
  In the production of recycled polyester fabric, energy consumption, emission of harmful gases (75% less CO2) and water consumption are minimized compared to the production of virgin polyester. It reduces dependence on petroleum as a raw material source, and helps promote new recycling streams for polyester waste.
  Our post-consumer recycled polyester is GRS (Global Recycled Standard) certified.
• Wool: A 100% natural, renewable and biodegradable fiber. Its production consumes little energy, as the lambs are raised outdoors, and when it is no longer useful for either the animal or people, it can be composted to fertilize soils.
  All our wool is from Merino sheep from Italy and is RWS (Responsible Wool Standard) certified.
• Corn leather: fabric obtained from the fibers of the corn cob. The result is a very soft and light vegan leather. It is used for shoes and other accessories.

All our dyes are water-based biodegradable and do not harm the ecosystem.

We manufacture our products in Barcelona and Alicante (Spain), Portugal, Buca-Izmir and Bursa (Turkey), Faridabad (India) and Shanghai (China), depending on the origin of the raw material.

Producing in the same country where the primary product is grown has a much smaller ecological footprint than transporting these raw materials unprocessed and making the garments locally.

For this reason, we produce in India and Turkey garments made from organic cotton, in China those made from hemp, in Spain those made from wool from Italy and in Portugal those made from natural fibers such as Tencel or EcoVero from Lenzing, Austria.

We provide the transparency and traceability tool BCOME in all our collections, with which, with a simple 'click', you can obtain data on the impact on the planet and people that has generated the production of each of our garments.

We have the Fairtrade seal, the leader in Fair Trade, as well as being the most reliable and recognized sustainable certification. And all the factories we work with comply with favorable working conditions, fair pay and environmentally friendly manufacturing, complying with BSCI and SMETA Sedex certifications.

In addition, our products are certified with the Global Organic Textile Standard (GOTS), Global Recycled Standard (GRS) and Organic Blended Content Standard (OCS), which take into account not only the raw material of a product, but all production processes along the entire supply chain.

We send our products in cardboard boxes and envelopes made of recycled kraft paper with FSC certificate, vegetable glue and biodegradable water-based ink.

The envelopes are reusable thanks to their two closures, so that the customer can reuse them in the case of a return, thus extending their useful life.

Our polybags are biodegradable or recycled plastic and all of them are recyclable.

Depending on the total purchase amount, we give away a Fairtrade certified cotton tote bag to promote the reduction of plastic bags. They come in different colors, collect them!

Our clothing is made in an environmentally friendly way and requires special attention and care to ensure the best maintenance and durability to accompany you for many years.

The quality of materials and workmanship are very important, but the care that prolongs the life of the garment, and keeps it looking its best, is the most important secret of sustainability.

For this reason, we recommend that you carefully read the care recommendations for each product. You will find them on the inside label of the garment and on the product page of our online store.

If you have any questions, please contact us at shop@thinkingmu.com.

Our priority is to offer you quality items that you can use for many years to come. We take very seriously the quality control of our products, of all the materials they are made of and of all stages of the production process. Even so, individual incidents may occur exceptionally.

If you have received a product with a quality problem or a small defect, you can request a replacement by writing to us at shop@thinkingmu.com. We will need you to send us a photo to be checked by our Quality Department. Once checked, we will arrange for the defective product to be picked up and a new one will be sent to you.

If the item in question is not available we will proceed to refund the item and find a way to compensate you for the inconvenience caused.

To be notified if the size of the desired garment becomes available again, click on the "Notify me when it arrives" button and enter your e-mail address.

When a model of the current collection is no longer available, it is not likely to be available again. At Thinking MU we are committed to a responsible production model and produce short runs on demand.

The models that we do replenish are the continuity products, a careful selection of pieces chosen by you to compose the best closet.
