Size Guide

Our Sizing

We design and produce all our styles and patterns in-house with our own team and we mostly follow a standard sizing system. However, some collections may have slightly different size charts from others.

You can check the specific size charts on each individual product page as the last picture. Our unit of measurement is inches (1 inch = 2.54 cm, 1cm = 0.394 inches). To use the size charts correctly, please see more below on how to get your measurements.

Our items are true to size based on the size charts. If you are not sure about your size and you are between two sizes, we would recommend to contact us at or through Instagram(@ravii.bkk) for one of our team members to help you choose the right size!

How do I get my measurements?

The following steps will help you measure your Bust, Waist and Hips accurately:

  • For your Bust, hold one end of the tape measure at the fullest part of your chest and wrap it around your body. The tape measure should go under your armpits and around your shoulder blades. Make sure the tape measure is horizontal and not twisted.

  • For your Waist, find your natural waistline by bending your torso to the side and noticing where the crease forms. This is usually above your belly button and below your rib cage. Wrap the tape measure around this point and make sure not to hold your breath or tighten your stomach.

  • For your Hips, stand with your feet together and measure around the widest part of your hips and buttocks. Use a mirror to check that the tape measure is parallel to the floor and not slanted.
