Retail Policies


Orders shipped to California will incur a 9.75% sales tax.


Items purchased from THINK SUBSTANCE are eligible for a full refund or exchange if returned within 30 days of purchase. During the holiday season (Nov 1st – Dec 25th), we will accept your return after 30 days so long as it is received by January 10th. For US customers, contact us for a prepaid shipping label to return your merchandise at no charge (free shipping both ways). Items must be unworn, unwashed, undamaged, unused, and with all original tags attached.

For exchanges or store credit, we accept items received up to 60 days after purchase. A small number of heavily discounted items may be marked FINAL SALE, in which case they are not eligible for refund, exchange, or store credit. Shipping charges on expedited orders are not reimbursed. For international customers, if your purchase is delayed in customs, contact customer service for approval for a late return.

Keeping Your Items in Returnable Condition. Please try your best to maintain items in pristine condition. All returned items must be unworn, unwashed, undamaged, unused, and with all original tags attached.

Clothing - Please be careful of makeup or deodorant rubbing off on the garment.

Damaged Items - If you receive an item that is damaged, please contact our customer service immediately.

How to Send Back Your Return or Exchange (US Orders) - All domestic orders ship with PREPAID return mailing labels. To ship an item back to THINK SUBSTANCE, simply pack your item and invoice into a USPS priority bag/box and affix the prepaid mailing label. To mail your package, you can:

Schedule a free pickup with your regular postal worker.
Simply drop your package in a mail drop box.
Drop your package off at the post office without waiting in line as the package is prepaid/ready to go.
Please indicate on your invoice whether you are exchanging or returning the item. For exchanges, please indicate the desired model/size. We also recommend placing your exchange on hold with customer service so it does not sell out while we await your package. Just call us or send an email with your order number and the item/size you would like on hold.

How to Send Back Your Return or Exchange (International Orders) - International exchanges and returns work the same as domestic exchanges and returns, but do not include prepaid return labels or refund return shipping costs. Send exchanges and returns to:

THINK SUBSTANCE strives to produce and offer first-run, defect free clothing. Please be aware that even such products are not entirely free of workmanship errors, including occasional missing threads and similar defects. Products subject to distressing as part of the styling are also subject to increased chance of defect and do tend to wear out faster than normal.

Customers are welcome to return any item they are unhappy with. US customers have free return shipping on all merchandise, regardless of whether it is defective. For international customers, we will reimburse return transport costs on items with major defects, but we will handle shipping reimbursement for minor defects such as missing threads on a case-by-case basis. In general, we will reimburse return shipping charges for minor defects a maximum of five times per year, per customer.

Many products, particularly those with distressed styling, do wear out or develop holes with regular wear-and-tear over time. THINK SUBSTANCE warranties all products to be free of such problems for the first 90 days from the time of purchase, and will replace or refund your purchase in the event such a problem occurs. After 90 days, we will attempt to assist with repairs, including providing replacement hardware such as lost buttons or broken snaps, but we will not provide a complete replacement or refund for an unrepairable product after 90 days.


Your privacy is always guaranteed when you shop with THINK SUBSTANCE. We will NEVER release any of your personal information to outside parties and you will never receive unwanted emails.

When you sign up with us, you will receive information on new styles and upcoming promotions, but you may request to stop receiving this information at any time. To stop receiving information, simply send an email request to
