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!

We made it faster. The Vanish Carbon 2 features a full-length carbon fiber plate, even more lightweight midsole foam for a soft feel, and improved flexibility. It"s ready to rocket you through a tough speed workout and obliterate PRs on race day. Negative splits? Oh, positively. We built it to perform by increasing the stack height from 33mm to 36mm, with Altra EGO PRO™ midsole foam that"s 32% lighter in weight. This updated foam is more pliable, for added cushion and response. An updated full-length carbon fiber plate delivers a 14% increase in asymmetry, allowing for a more natural (and probably faster) stride. This redesign overhaul combined with additional flex grooves in the outsole gives you 75% improved flexibility. With Altra"s signature FootShape fit, you get a roomy toe box with space for your toes to move freely, snug midfoot, and zero drop, so you can move the way you were designed to. Toe the starting line with confidence and swag in this techy race-day ready shoe.
