Hi there! Thanks for reaching out to TRIANGL Support. We’re happy to help.
The Vinca Pollo Geometric Triangle Bikini Set is sold as a complete set, meaning you need to add both the top and bottom together. The top in size M and normal fit is in stock, but some bottom variants, like the cheeky fit in size M, are currently out of stock. If you tried selecting a bottom size or fit that isn't available, that would prevent adding the set to your cart.
Please try selecting an in-stock combination of top and bottom to add the bikini set successfully. Let me know if you need further assistance!
