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!

The pressure is on smaller toes on outside of foot.

Shoes Width Guide
The standard (medium) width for unisex shoes is D. Shoe boxes and labels will only identify widths other than standard. Within the shoes, wide and narrow widths are identified on the label, underneath the tongue.
When is additional shoe width needed?
Visible stretching or bulging on the sides of the forefoot material is a good indicator that additional width may be needed.
Please note that the differences in width between narrow, standard, wide, and extra wide are usually only a few millimeters and are proportional to the shoe size. Most of the additional width will be in the forefoot
