If you fancy a Sienna Miller, feminine boho chic look this summer why not go for a wide brim straw hat. These are very flattering and offer maximum protection for your face and eyes when the sun comes out.

There are many different styles and colors of wide brim straw hats, but the actual trick to finding one that suits you is to understand your face shape. Here is a quick guide for common face shapes and what to look for in a hat with a wide brim.

If you have a cute round face like Cameron Diaz follow her styling tips and aim to elongate the face when wearing hats. Therefore opt for a wide brim that is irregular in it shape and is not completely horizontal so try a hat where the brim tilts slightly. You should also opt for a crown that has height which will give the illusion of a longer face . If you want to wear other accessories with your hat again the aim is to elongate, so with earring for example try and go for long sleek pair rather than chunky shapes.

For those ladies that have the same sexy square shape as Angelina Jolie go for a hat with a curved wide brim that you can tilt very slightly to one side, this softens the jaw line and still allows you to show off those strong cheekbones.

Finally those lucky beauties who boast a sweet heart shape face like Reese Witherspoon, will find that hats where the crown is prominent will help slightly lengthen the forehead giving the face more balance. Hats with a large straw brim that are slightly floppy look great on this face shape.
