FAQ's

It depends on the style. We restock select core items when possible, while seasonal or limited-run styles may not return once they sell out. Returns can occasionally reappear as available inventory, so it’s worth checking back. If a size or color you want is unavailable, use the “Notify Me” option on the product page to get an alert if it comes back.

Once your order ships, you’ll receive a shipping confirmation email with a tracking link. Tracking will start updating after the carrier receives and scans the package.

Carrier systems sometimes take time to show the first scan or movement. If it’s been [2–3 business days] with no update, contact us with your order number and we’ll help.

If the tracking shows “delivered” but you don’t see it, check the delivery area (front door/side door), building mailroom/front desk, neighbors, and any alternate entrances. If it’s still missing, contact the carrier first, then reach out to us and we’ll assist with next steps.

During busy periods (launches, promotions, holidays), processing times may be longer than usual. We ship as quickly as possible—if you need an update, email us with your order number.

International customers are responsible for any duties, customs fees, and local taxes charged by their country. Please double-check that your address is complete and accurate before placing your order.

If your tracking indicates an ETA-style last-mile carrier, and you have questions about delivery timing, contact us with your order number and we’ll help you understand the next steps.

We begin processing orders quickly, so edits aren’t guaranteed. If you contact us right away, we’ll do our best to help if your order hasn’t entered fulfillment.

Cancellations are not guaranteed once an order is placed. If you reach out immediately, we’ll try to accommodate when possible and confirm what options are available.

All returns must be initiated through our online return portal so we can track your request and process it properly.

Once your return arrives and is inspected, refunds are typically processed within [5–7 business days]. You’ll receive an email once your refund is issued. (Timing for funds to appear can vary by payment method.)

We don’t offer direct exchanges at this time. If you need a different size or style, please return the original item in eligible condition (per our return policy) and place a new order for the correct item.

Eligibility depends on how the item was labeled at checkout. Items marked Final Sale are not eligible for return. For other discounted purchases, please refer to our full Return Policy for the most up-to-date terms.

If your return causes your order to no longer qualify for a promotion (for example, a bundle or threshold discount), we may adjust the refund to reflect the value of the promotion, or require the promotional item be returned in new condition.

Please initiate a return through the return portal and select the option for incorrect or damaged items. Follow the prompts so we can resolve it as quickly as possible.

We can only process returns for items purchased directly from the Mirellie website. If you purchased through a retail partner, please contact the store you purchased from for their return process.

Most styles are designed to fit true to size. If a specific item runs differently, we’ll note it on the product page. If you’re between sizes or want guidance, reach out—we’re happy to help.

For best results, follow the care instructions on the garment label. In general, we recommend washing in cold water on a gentle cycle, using mild detergent, and avoiding high heat in the dryer. For delicate items, consider hand-washing or laying flat to dry.
