Below are size charts for different products. Find the size that's right for you. It is important to be familiar with your own size when choosing a dress size. Only by knowing your personal measurements can you get the best fit. Each designer may define sizes differently—what is a size 6 in your everyday garments might be a size 10 in our dresses or another designer's.

Best silhouettes:
- Empire waist or high-waist styles
- A-line dresses with flowing skirts
- V-necklines to elongate the torso
- Ruched or draped fabric at the waist
Tip: Look for styles that create a defined waistline just below the bust for a flattering silhouette.

Best silhouettes:
- Ball gowns and princess-line dresses to add volume
- Peplum or ruffled styles to create curves

Best silhouettes:

- V-neck or sweetheart necklines to soften the shoulder line

Defined by: Shorter overall frame (typically under 5'4" / 163 cm).
Best silhouettes:
- High-waist or empire styles to elongate legs
- Shorter hemlines or high-low styles
- Vertical details, thin straps, and minimal bulk
- Column or sheath gowns for a sleek line
Tip: Avoid overly voluminous skirts that can overwhelm a petite frame — opt for clean, elongating lines.
Measurement Guide
Please check bust, waist and hips when choosing a size. To learn how to measure, follow the instructions below.
Bust
This is the measurement around the fullest part of your bust (body circumference at the level of the breasts). Wrap the tape around the fullest part and keep it level across the back.
- This isn't your bra size.
- Keep your arms relaxed by your sides.
- Wear the bra you plan to wear with the dress when measuring.
Waist
Measure your natural waistline (the smallest part of your waist). Keep the tape parallel to the floor. Bend to one side to find the natural crease—this is your waist.
Hips
Measure around the fullest part of your buttocks, usually 7–9 inches (18–23 cm) below your natural waistline. Keep the tape parallel to the floor all the way around.
Hollow to Floor
Hollow to Floor (barefoot): hold the tape at your center collarbone (hollow) and have a friend pull it straight down to the floor.
Back Shoulder Width
Measure from the edge of the left shoulder across the prominent neck bone at the back of the neck to the edge of the right shoulder. Place the tape on top of the shoulders.
Sleeve Length
Measure from your shoulder seam to where you'd like the sleeve to end, with your arm relaxed by your side.
- Tip: measure with your arm slightly bent.
Armscye (Armhole)
Wrap the tape over the top of your shoulder and around under your armpit to measure the armhole.
Arm Circumference
Measure around the fullest part of your upper arm.
- Tip: keep the muscle relaxed.
