Hi there! Thanks for reaching out to TRIANGL Support. We’re happy to help. Based on your measurements with an underbust of 31 inches and overbust of 35 inches with a B cup, the recommended size for TRIANGL tops is generally size S. This fits an underbust between 75–80 cm (approximately 29.5–31.5 inches) and overbust between 83–87 cm (approximately 32.7–34.3 inches), which corresponds well with your measurements. TRIANGL tops have a firm swimwear fit, so it's good to check the updated size guide on their website for more details. If you'd like, I can connect you with a sizing expert to double-check your size choice — just let me know!

The Small+ size is designed for customers with a smaller frame but a fuller bust, offering about 1 cm more bust coverage than the regular Small. Since your underbust is 31 inches and overbust 35 inches with a B cup, the regular Small usually fits well. However, if you prefer more bust coverage or support, Small+ could be a good option for you. TRIANGL tops have a firm fit, so sizing up to Small+ can provide extra comfort or support.
