Tip
Between sizes? For structured or non-stretch fabrics, we recommend sizing up. For stretch styles, choose the smaller size for a close fit.
Our dresses are designed for a modern, tailored silhouette. Standard allowance is ±2 cm (±0.8”) due to cut and fabric.

How to Measure
Bust
Measure around the fullest part of your bust with the tape parallel to the floor. Keep it snug but not tight. Wear the bra you plan to style with the dress.
Waist
Measure around your natural waist — the narrowest part of your torso, typically just above the navel.
Hips
Stand with feet together; measure around the fullest part of your hips and seat (usually ~20 cm below the waist).
Shoulder
Across the back from shoulder tip to shoulder tip.
Inside leg (inseam)
From crotch to ankle bone; useful for jumpsuits and pants.
Fit Types
Fitted
Closely hugs the body with minimal ease. Best for structured satin or crepe.
Tailored
Defined bust and waist shaping for a polished silhouette — our signature evening fit.
Relaxed
Looser drape through body and skirt for movement and comfort; ideal for resort styles.
Stretch
Body-skimming with elastane; size down for a close fit or choose true size for comfort.
Flowy
Romantic ease with minimal waist definition; floaty chiffon and satin bias cuts.
Fabric & Stretch Guide
No stretch Woven satins, crepe, taffeta — choose your larger measurement for a tailored fit.
Light stretch Bias-cut satins, stretch crepe — true to size with gentle hold.
High stretch Knit jersey, ponte — consider sizing down for a sculpted look.
Care
Follow garment care labels. Steam rather than iron where possible. For alterations, we recommend a professional tailor experienced with delicate satins.
FAQs
I'm between sizes — what should I choose?
For non-stretch or fully lined styles, we recommend the larger size; for stretch styles, choose the smaller size for a sleek fit.
How accurate are the measurements?
Each garment is cut by hand; allow a tolerance of ±2 cm (±0.8”). Fabric properties can also affect drape and ease.
Do you provide a sizing concierge?
Yes — share your bust, waist, hip and height via chat or email and our team will recommend the best size and styles.
