Frequently Asked Questions
SIZING & FIT
The pieces are unisex, how do they fit men vs women?
Our pieces are designed to fit well on everyone. The fit is relaxed without being oversized, so it works across body types. Women who prefer a more fitted look usually size down one. Men typically find their regular size works well. When in doubt, check the size guide on each product page.
Should I size up or down?
It depends on how you like to wear it. If you want a roomier, more relaxed fit, go up one size. If you prefer it closer to the body, stick with your usual size or go down. The size guide has chest and length measurements to help you decide.
What if it doesn't fit?
No problem. You have 14 days to return or exchange. The item just needs to be unworn and in its original condition. Head to our returns page to get started.
MATERIALS & CERTIFICATIONS
What does OEKO-TEX Standard 100 actually mean?
It means every part of the garment, the fabric, the thread, the zippers, the labels, has been independently tested against more than 1,000 harmful substances. It's one of the most recognised textile safety certifications in the world, and it's verified by a third party, not us. You can check our certificate directly on the OEKO-TEX website using our licence number; 13.HTR.22116.
How does OEKO-TEX Standard 100 compare to other certifications?
OEKO-TEX Standard 100 is a finished product certification. It means the garment in your hands, every component and every stitch, has been independently tested against more than 1,000 harmful substances. GOTS is a process certification that covers the entire supply chain from raw fiber to finished product, but requires a minimum of 70% organic content. Fair Trade focuses on worker conditions and pay rather than the product itself. Svanemerket covers both environmental impact and chemical safety but is broader than textiles alone. OEKO-TEX Standard 100 is the most widely recognised textile safety label in the world, and it is the one we can stand behind for every piece we make.
What materials do you use?
Our hoodies and sweatpants are made from an 80% cotton, 20% polyester blend. The cotton keeps the fabric breathable and soft against the skin. The polyester is there to help the garment hold its shape after washing and adds to the overall feel.
What GSM is the fabric?
Our hoodies and sweatpants are made from 380gsm cotton blend. That's on the heavier end for a reason. It holds its shape, feels substantial, and wears well over time.
CARE & WASHING
Will my garments shrink in the wash?
We test production samples for shrinkage and colorfastness before anything goes into production. Wash cold and avoid high heat and you'll be fine.
How do I wash my Sunday Superior products to make them last?
Turn it inside out, wash at 30 degrees or cooler, and use a gentle cycle. Skip fabric softener, it breaks down the fabric over time. Line dry when you can. That's really all it takes.
Check our full care and maintenance guide for step by step instructions on removing grease, blood, coffee, red wine, chocolate, chewing gum, candle wax, lipstick and makeup.
Can I tumble dry?
We'd recommend skipping the tumble dryer. The heat puts stress on the fabric and will cause more pilling over time. Line drying keeps it in better shape for longer.
SHIPPING & DELIVERY
Where do you ship?
We ship to Norway, Sweden, Denmark, Finland, France, and Germany.
How long does delivery take to Norway / Europe?
Orders to Norway arrive within 7-8 business days, and most of Europe arrive within 10-12 business days. Delivery time may vary depending on destination.
You'll get a tracking link as soon as your order ships.
RETURNS & EXCHANGES
How do I return or exchange?
You have 14 days from delivery to return your order. Items must be unused with all tags attached. Full details and instructions are on our returns page.
What if my item has a defect?
That shouldn't happen, but if it does, we want to sort it out. Send us a photo and your order number to support@sundaysuperior.com and we'll take it from there. Manufacturing defects are always covered.
SUSTAINABILITY
Where are your clothes made?
All our products are made in Istanbul, Turkey, by a long-term partner with audited working conditions. Safe workplaces and fair pay are non-negotiable for us. We visit, we ask questions, and we don't just take paperwork at face value.
How do you make sure factories treat workers fairly?
We work with audited factories and visit them regularly. Our partners must meet strict standards on pay, working hours, safety, and no child or forced labour. We choose fewer, better partners over a wide supplier base we can't keep track of.
PRODUCT & QUALITY
Why does GSM matter in a hoodie?
GSM stands for grams per square metre and tells you how heavy and dense the fabric is. Most high street hoodies sit somewhere between 280 and 320 GSM. Ours are 380 GSM. That extra weight means more cotton in the weave, which translates to a better drape, more warmth, and a garment that holds its shape over time rather than thinning out after a season of wear. It is the difference between a hoodie that feels substantial and one that feels like a t-shirt with a hood.
Will the color fade after washing?
We run colorfastness testing before production starts to make sure the colour holds. Wash cold and line dry and it'll stay true for a long time.
How does the hoodie hold up over time?
Our 80% cotton, 20% polyester blend is chosen specifically because it keeps its shape. The polyester content means the fabric bounces back after washing and holds its structure through regular wear. Built to last, not just to feel good on day one.
Are there more styles coming?
Yes. We keep the range tight on purpose, but we're always working on what comes next. Sign up to the newsletter to hear first.
