  • I just placed an order. When will my package arrive?
    Orders can take up to 2 weeks to ship depending on inventory or if your order is custom. We are a small business based in Los Angeles, so please be patient with us :) We do offer same day shipping on certain items, which will be noted in the description section of the item. Overall, please allow up to 2 weeks (14 business days) for your order to ship, but we'll do everything we can to get it to you sooner. If you need your order by a certain date, send us an email or DM and we will do our very best to accommodate you!
  • Where is my order?
    You will receive a shipping confirmation email with tracking info as soon as your order ships. Once your package has been received by USPS, it is out of our hands. If your package shows delivered, but you have not received it please reach out to USPS Customer Service at 1 (800) 275-8777. USPS will allow you to file a claim. ​ If you live in an area with a high risk of package theft, please reach out to us when you place your order to request a "signature required" delivery. Cosier is not reliable for any misplaced or stolen packages if the address provided matches with the address we have shipped your order to. If your tracking number reads as successfully shipped, stolen/lost packages are nonrefundable. If it has been over 2 weeks and you have not received a shipping confirmation email from us, please send us an email at or DM and we will take care of you!
  • What is your return/exchange policy?
    All sales are final! You may exchange any item for a different size within 10 days once your order is marked as "delivered" on your tracking link. The item(s) must be unworn and in the same exact condition as received. If you would like to exchange an item, send us an email at and we will issue a return label. If you purchased an XXL item and it does not fit, you can return it and we will issue a refund since we do not have larger sizes at the moment.
  • How do you pronounce Cosier?
    Cosier has a French pronouncation, like Cosy-eh. The name of our brand is just Cosier, not Shop Cosier.

  • How do I figure out my size?
    Our size charts are located in the image section of each product. If you have further questions about sizing, just send us a DM and we'll help you figure it out!
  • What are the gemstone sets made out of?
    The pendants attached to our Gemstone hoodies are made with natural gemstones set in golden metal. They are druzy agate, meaning they are created from small crystals on a mineral surface. They are formed with various stones including agate and quartz!
