SixteenOS Questions & Answers

What types of products does SixteenOS sell?
SixteenOS focuses on lifestyle apparel and accessories — typically wardrobe staples like tees, hoodies, outerwear, and complementary accessories such as bags, caps, or eyewear. The emphasis is on minimalist design and durable materials.

What is the shipping policy and delivery timeframe?
Most DTC lifestyle stores offer standard domestic shipping (3–7 business days) with expedited options for faster delivery. International shipping is usually available with longer transit times and customs fees. Exact costs and times should be listed on the site’s shipping policy page.

What is the returns and exchange policy?
Commonly, stores accept returns within 14–30 days of delivery for unworn, unwashed items with tags attached. Exchanges for size or store credit options are often available. Check the site’s returns page for exceptions and instructions.

How do I choose the right size?
Look for a detailed size guide on each product page and measurement charts. If available, customer reviews often include fit notes (true to size, runs small/large). Contact customer support for personalized recommendations if unsure.

Are there sustainability or material details provided?
Product pages typically include material composition and care instructions. Many modern brands highlight sustainable choices like organic cotton, recycled fabrics, or low-impact dyes — look for those notes in the product description or an “Sustainability” section.
