Hi Tania, Thank you for your feedback.
The Moli bikini tends to run small, and we recommend sizing up if you're between sizes — as mentioned in our product description 'Size Consideration: Run Small, Choose one size up if you are in between sizes', and also by other customer reviews.
Additionally, the Moli bikini is part of our sale section, which is non-refundable, as clearly stated in our refund policy. We understand how frustrating it can be when an item doesn’t meet your expectations, and we’re sorry for any inconvenience this has caused.
For shipping fee, we charge a shipping fee of 10 CHF to Switzerland. Any additional import duties or taxes are beyond our control.
If you need further assistance, please don’t hesitate to contact us at care@calaswim.com.
