Loud & Proud Prints
Busy, vibrant prints trick the eye into perceiving more surface area and movement, making your bust appear fuller than it would in a flat, solid color.

- -Animal Prints: Naturally creates dimension - our current favourite has to be the classic leopard print as seen with the Santorini Balconette Bikini.

The Power of Horizontal Stripes
You’ve probably heard the old fashion myth that horizontal stripes make you look wider. Well, when you have a smaller bust, you can use that exact rule to your absolute advantage!
Horizontal lines draw the eye outward, creating a widening effect. A bikini top or one-piece featuring horizontal stripes across the chest instantly creates the illusion of a broader, more filled-out bustline.

Color placement is everything. Dark colors minimise and recede, while bright, light colors highlight and bring features forward.
By wearing bright colors such as neon pinks, electric blues, sunny yellows, and crisp whites—on your top half reflects more light, making the area appear larger and more prominent.
