SHOES

We are currently using Asian/European sizing for our footwear. To find your best fit, follow these steps:

Measure your foot
Place the back of your foot against a wall on level ground. Then measure the distance from point A to B.

The distance between A and B is the length of your feet.
Select your size
Refer to the size conversion chart below and select the size closest to the length of your feet.

Size Chart for Adults

CHARLES & KEITH uses Asian/European size for its footwear collection.
If both sides of your feet are different in length, we recommend you select a shoe size based on the longer side.
The current recommended size chart does not include half size recommendations. We suggest you select the shoe size based on the length closest to your feet measurement.
Please note, foot length is not equivalent to shoe length.
Shoe comfort is dependent on a combination of factors such as size, design/cutting and heel height. For example, shoes that are of the same size, but are different in design/cutting, may not give you the same level of comfort.
These are recommended guidelines to get you the best possible fit for CHARLES & KEITH footwear collections only.

BELTS

Refer to the size chart below and select the belt size closest to the length of your waist/or hip, according to the belt type.

Belt size chart
TYPE	SIZE	WAIST
HIGH WAIST	S	65cm/25.63"
	M	75cm/29.5"
	L	85cm/33.5"
MID WAIST	S	70cm/27.5"
	M	80cm/31.5"
	L	90cm/35.38"
LOW WAIST	S	80cm/31.5"
	M	90cm/33.38"
	L	100cm/39.38"

This size chart is based on the belt type and can vary when worn at a higher or lower level.
The size of a belt indicates the measurement from the buckle prong (or other methods of closure) to the middle hole of the belt.

These are the recommended guidelines to get you the best possible fit for CHARLES & KEITH belt collections only.

RINGS

Refer to the size chart below and match the ring size closest to the diameter provided.

Ring size chart
SIZE	DIAMETER
S	16.8mm/ 1.68cm
M	17.7mm/1.78cm

Use this chart as a general guide. Sizing may vary depending on the shape of the ring.
Do choose a size that allows your finger to pass through the ring easily.
