Once you know what sort of frame suits your face, why not think outside the square; go for coloured glass, reflective shades or patterned frames if your really brave. Here are my pick from the High Street shops as well as some at the upper end of the scale.
SQUARE
Try curvier frames like round, oval, cat eye, butterfly and semi-rimless to accentuate your eyes and playfully balance a striking jawline.
Glassons Metal Bridge Cat-eye Sunglasses $24.99, Kate Sylvester Camilla $349.00, Glassons High Temple Wayfarers $19.99.
You can pull off just about any look when it comes to sunglasses. Rectangle frames are often chosen for their horizontal orientation to balance an oval vertical face.
SEED Heritage Olivia Metal Arm Sunglasses AU$49.95, Witchery Niki Sunglasses $79.90, Karen Walker Harvest Collab Blue Liberty Print $429.00.
Geometric shapes like horizontal frames, Wayfarers and rectangle shapes will give your face a longer, thinner look.
Sunglass Hut Doce & Gabbana Urban Essentials AU$410.00, Sunglass Hut Ray-Ban Blue Wayfarer $179.95, Witchery Izabel Wayfarer $79.90.
Light-colored frames, frames with thin temples, or frames with exaggerated bottoms for heart shapes.
