Perfectly Proportioned
After months of listening to you—through detailed surveys, interviews, and community feedback—we're proud to introduce our first-ever Petite collection. We heard your frustrations around fit, length, and proportion, and we’ve taken all of it on board to create a range designed specifically for women 5'4" (164cm) and under. This is not just a smaller size scale—it’s a complete reimagining of our signature silhouettes, carefully adjusted to flatter petite proportions without compromising on style.
From perfectly-fitted dresses to polished separates, each piece features refined lengths, tailored silhouettes, and the same premium fabrics you already love. Available in sizes 0P–5P (AU6–AU16), this exclusive, limited quantity edit brings effortless elegance and wearability to your wardrobe—no tailoring required.

Finding Your Perfect Fit in the Petite Edit
To ensure you find your best size in our new Petite collection, we’ve included detailed garment measurements on each product page. These measurements are taken with the garment lying flat, so you can easily compare them with similar items in your own wardrobe.
If you have a tape measure handy, we recommend measuring a comparable piece and matching it to our size chart for the most accurate fit. Each products size chart can be found under 'Size and Fit' on their product page
Here’s how to measure:
TOPS
Bust: Measure straight across just below the armhole from side to side, then double the number.
Waist: Measure at the narrowest part of the garment or at the waist seam.
Measure approximately 20 cm below the waist.
BOTTOMS
Waist: Lay the waistband flat and measure straight across from side to side. Then double the measurement.
Hips: Measure 20 cm down from the top of he waistband across the widest part of the hip area, then double that number.
Once you have your garment’s flat-lay measurements, compare them to your body measurements—ensuring the garment is a few centimetres larger for a comfortable fit.
