Yes — we provide a detailed Size Guide for every product to help you find your best fit.

You can access the size chart directly on each product page.

If you’re unsure between sizes, we recommend choosing based on your preferred fit (more relaxed or more fitted), or reaching out to our customer service team for personalized advice.

The best choice depends on the specific style and how you like your clothes to fit.

For example:

• If you prefer a more fitted look, you may consider sizing down
• If you prefer a relaxed or effortless fit, we recommend sizing up

Because fabric, cut, and design can vary across styles, we also recommend checking the product description for fit notes on each item.

At Tankaneo, we are committed to creating styles that feel inclusive, wearable, and thoughtfully designed.

While not every style is currently available in plus sizes, we are continuously working to expand our size range and improve inclusivity across future collections.

We truly value customer feedback - your input helps us shape what comes next at Tankaneo.

If there’s a style you’d love to see in your size, feel free to reach out to us anytime.

At Tankaneo, we offer a limited price adjustment policy to ensure fair pricing while protecting promotional campaigns.

• Price adjustments are not available on promotional discounts, including percentage-off or fixed-amount offers (e.g. 25%, 40%, 50% off, or $ off campaigns)
• A one-time price adjustment may be offered if an item you purchased at full price is marked down for the first time
• The request must be made within 7 days of the original purchase date
• Price adjustments are only applicable for orders placed on our official website

Please note that we are unable to process price adjustments for orders placed outside Tankaneo.com or through third-party platforms.

We begin processing orders shortly after they are placed to ensure fast shipping, so we’re usually unable to cancel or make changes once an order has been confirmed.

If you need to cancel or modify your order, please contact us as soon as possible after placing your order. Orders may only be changed or cancelled if they have not yet been processed or shipped.

If your order is still eligible, we may be able to assist with:

• Updating your shipping address
• Adjusting sizes or items (subject to availability)
• Removing items from your order

Once an order has been shipped, it can no longer be cancelled or modified and will need to follow our return process after delivery.

Please note that all cancellation requests are subject to confirmation from our customer service team. Be sure to include your order number to speed up the process.

At Tankaneo, customer satisfaction is always our priority. We want you to feel confident with every purchase.

• Returned in original packaging where applicable
• Purchased directly from Tankaneo.com

Please note:

• Return shipping costs are the responsibility of the customer
• Original shipping fees are non-refundable
• Certain items (such as final sale products) may not be eligible for return
• We do not accept returns for items not purchased from our official website

If you receive a damaged, defective, or incorrect item, please contact us within 7 days of delivery with your order number and clear product photos. Once verified, we will offer a replacement or refund, including applicable shipping costs where relevant.

For returns due to personal reasons (such as size, style, or change of mind), refunds will be issued for eligible item value only after inspection.

At the moment, Tankaneo only ships within the United States.

We’re sorry for any inconvenience this may cause. Currently, we do not support international orders, so all shipping addresses must be U.S.-based.

If you have any questions about shipping or would like to be notified when we expand to international delivery, feel free to contact our customer support team.
