Hi there! Thanks for reaching out to TRIANGL Support. We’re happy to help.
The '+' in the sizing guide, like S+ or S++, indicates designs for customers with a smaller frame but a fuller bust. Each '+' size offers about 1 cm more bust coverage than the previous size, while keeping the same underbust measurement as the standard size.
If you want more personalized sizing help, just let me know! For more details, you can also check out the official sizing guide on our website.
