To find your size when buying online, follow these steps:

1. Measure the body: Use a tape measure to measure your chest circumference, waist, hips, and body length. You can also use your previous measurements as a reference.

2. Check sizing charts: Check out the size charts on the seller’s website, as they provide guidance on how to choose the right size based on your measurements.

3. Read customer reviews: Read customer comments about the clothes they bought, and learn from their experiences regarding the size and fit of the clothes.

4. Look for additional information: Some sellers may provide additional information about the garment such as length measurement and recommended weight for each size, which can help with decision-making.

5. Take advantage of return policies: Make sure the retailer has a flexible return policy that allows you to return or exchange clothes if they don’t fit you properly.

By following these steps, you can increase your chances of getting the right size when buying online.
