Please be assured it is normal for seamless swimwear to fold over slightly showing the reverse side. All colour tones of our swimwear are designed with this in mind.


Our fabric is a blend referred to as Italian Lycra. Please note the feel is intended to be soft & delicate. Our swimwear remains durable so long as it is cared for appropriately. We provide care instructions on purchase.


Please note pastel colours may become opaque when wet. Neon colours may run for initial washes. Please see our Frequently Asked Questions for more details & care instructions.
