Our models typically wear US Size 2-4 or Australian Size 6-8, X-Small, Small, or One-Size garments.
On each product page, we provide the model's measurements and what size she is wearing to help guide you.
You can refer to the charts when selecting sizes but please note that sizes cannot be guaranteed and might vary slightly between brands.
If you need any advice about sizing, please feel free to drop us a line at: service@sunnoss.com
The measurements in the description of individual products are taken only across the front side of the garment, not around the circumference (e.g. chest and waist).
If you can't find a completely satisfactory size in our size chart, don't worry! Feel free to contact us anytime at service@irispetal.com or through our online customer service. Our team is more than happy to provide personalized advice, recommend alternative styles, or assist with customization needs. Your comfort is our top priority!
