Hi Michelle,

We appreciate the interest you show in purchasing from our website.

Due to slight differences in item sizing between manufacturers, we have created our own size chart. You can be assured that items are consistent with our size chart with an allowable deviation of only 2 centimeters for our Baby & Toddler products, 4 centimeters for our regular selections for Men and Women, and 5 centimeters for our Maternity/Nursing selections.

For the best fit, we do recommend buyers to not base their choice on the size they normally purchase, but to use a measuring tape and compare your measurements with our size chart. When measuring around your body, such as bust, waist, and hips, you want to ensure that it is as horizontal as possible. Ensure that the measuring tool is always close against your body, but don't hold it too tight. The general rule is close but comfortable - not tight and not loose. You may also measure a similar style of clothing you currently own, that fits you well, and compare which size it corresponds to on our size chart.

Feel free to contact us at https://us.patpat.com/article/help/contact if you have further inquiries for more detailed information.

Have a great day!
