This guide gives you: (1) a simple reminder of body shapes (A, V, X, H, O); (2) suitable cuts , with advantages/disadvantages; (3) advice on materials, colors, lengths , and adjustments to avoid returns.

Understanding your body shape (in 2 minutes)

Your body shape is not a clothing size: it is the distribution of volumes .

Morphology A (pyramid)

• Shoulders narrower than hips ; waist often marked.
• Objective : rebalance by structuring the top and flaring the bottom .

If you have wider hips than shoulders , and your figure seems to "widen towards the bottom," then you probably have an A-shaped body , also called a " pyramid ."

It is one of the most common silhouettes among women.

The upper body is often slimmer, more delicate, sometimes with slightly drooping shoulders and a rather small chest. On the other hand, the buttocks, thighs and hips are more prominent.

It's a super feminine body shape, all softness with a creative and generous energy. And you share this type of silhouette with none other than Beyoncé or Jennifer Lopez: badass and ultra glamorous!

Morphology V (inverted pyramid)

• Broad shoulders , narrower hips ; legs often long.
• Objective : soften the top, add volume to the bottom.

Do you have shoulders that are broader than your hips ? A defined build , a slightly understated waist, and a rather narrow pelvis ?

You're probably on the V-shaped body type team , also known as the " inverted pyramid ."

It is a dynamic silhouette, often associated with a sporty or assertive posture.

Your gaze naturally falls towards the upper body: the shoulders are visually dominant, while the lower body is slimmer and more discreet.

If you've ever felt like a pair of pants were a little baggy when a top fit perfectly... It's probably because you're a V.

And you share this type of silhouette with Angelina Jolie or Cameron Diaz: elegant, powerful, confident.

X-shaped body (hourglass)

• Shoulders and hips aligned, waist marked .
• Objective : to emphasize the waist without compressing the volumes.

You are one of the women who have an X- shaped silhouette if your shoulders and hips are aligned , and you have a defined waist.

This is also called the "hourglass" silhouette : everything is well proportioned, smooth and harmonious.

Visually, the line of your silhouette forms an "X", hence its nickname.

This X-shaped morphology is often considered balanced, because the volumes are distributed fairly symmetrically between the upper and lower body.

It is also the twin morphology of the 8 silhouette, with one difference: the X is often thinner, with lighter curves.

Morphology H (rectangle)

• Shoulders/hips aligned , waist slightly defined .
• Objective : To create an illusion of size and movement.

Are your shoulders, waist, and hips aligned ? Do you have a fairly straight silhouette, with no significant difference between the top and bottom? Welcome to the H-shaped body type team, also known as the " rectangle ."

Your waist is not very defined , but your silhouette remains balanced, refined, elegant.

The body forms an almost straight line, without sharp angles, with a natural and fluid appearance.

Many women with this body shape say to themselves "I don't really have a shape"... But in reality, it's an ideal base for creating style !

And you're not alone: Keira Knightley, for example, perfectly embodies this chic, structured silhouette.

Figure 8 Morphology

Do you have aligned shoulders and hips , a well-defined waist, generous curves , and a curvy silhouette? Then you are undoubtedly part of the figure 8 team.

It's the curvy cousin of the X-shaped body: same balanced structure, but with more volume in the chest, hips or buttocks.

And to inspire you: Monica Bellucci is the perfect embodiment of this silhouette. Sensual, elegant, full of presence.

Morphology O (round)

• Generous curves, belly at the center of the silhouette, soft shoulders.
• Objective : lengthen the line, smooth out the fall, mark vertically.

If you have a soft silhouette, with generous curves , a defined chest , a small belly , and rounded shoulders , then you are undoubtedly in the O body type category.

Here, the volumes are rather concentrated around the center of the body , with a slightly marked waist and a feminine, voluptuous look.

Your silhouette forms a rounded, harmonious and full of softness, hence the name "O".

You may recognize yourself in this body shape if you often say to yourself "I am curvy", or "I feel round".

And you know what? You're far from alone: the singer Adele, for example, perfectly embodies this silhouette. Charismatic, assertive, radiant!

Quick tip – if you’re unsure: take your chest/waist/hip measurements.
• A: hips > shoulders by 4–8 cm • V: shoulders > hips by 4–8 cm • X: shoulders ≈ hips, waist –20 cm approx. • H: shoulders ≈ hips, waist –0 to –10 cm • O: waist measurement close to chest and hip measurement

Combine cut & morphology (quick references)

A (marked hips)
✔ A-line, Empire, Princess, Mermaid (if regular hips) • ✖ Puffy shoulders without volume at the bottom

V (broad shoulders)
✔ A-line, Princess, Asymmetrical/One Shoulder, Sheath with Slit • ✖ Structured shoulders + straight bodice too rigid

X (thin waist)
✔ Mermaid, Sheath, A-line, Princess • ✖ Empire too loose (risk of erasing the waist)

H (little height)
✔ A-line, Princess (creates a waist), Asymmetrical, Belted Sheath • ✖ Very smooth bodycon with no waist marking

O (round)
✔ Flowing empire, A-line, V-neck, cape sleeves • ✖ Ultra-thin bodycon, too-tight waistbands

Materials & finishes: what makes all the difference

• Duchess satin / mikado : outfit, luxury, ideal sheath/princess .
• Crepe : clean, smooth fall, perfect sheath/mermaid .
• Chiffon / georgette : fluid, airy, perfect empire/A-line .
• Tulle : volume without weight, princess .
• Thick jersey / scuba : tight but smoothing, for bodycon/mermaid .
• Sequins : reflect light; prefer simple cut if fabric is already strong.
• Lace : softens, adds relief; favor smooth lining .

Golden rule: strong fabric = simple cut . If you choose intense sequins, keep a clean line to stay chic.

Colors (depending on lens)

• Lengthen/refine : dark and monochrome colors (black, navy, burgundy).
• Brighten the complexion : jewel tones (emerald, sapphire, ruby), cool pastels if fair skin, warm if golden skin.
• Balance A/V : light where you want to draw the eye , darker elsewhere (e.g. A: light top / dark bottom).

Length & slits

• Long : very dressy, slender with heels; hem 1–2 cm from the floor with heels.
• Midi (mid-calf): ultra trendy, shows the ankle (thin sandals).
• Mini : cocktail evening; balance with long sleeves if fitted cut.
• Slit : straight/centered for chic, side for a slender leg (pay attention to sitting comfort).

Size & adjustments (anti-return)

1. Measure bust/waist/hips (in cm) and compare to the FR/US chart .
2. Between two sizes → take the larger one and adjust (hem, waist).
3. Bra : provide adhesive /strapless for bustier, backless for plunging back.
4. Thin belt : creates a waist on H and secures the mermaid.
5. Personalization : if offered, indicate color + measurements (chest / waist / hips) and length with heels .

Accessories that complete the silhouette

• Belts : jewels or tone-on-tone satin to accentuate the waist.
• Jewelry : No more than one statement piece (large necklace or statement earrings).
• Soft shoulder pads / cape : slims an arm, structures the top.
• Bag : Rigid minaudière for mermaid/sheath, soft clutch for empire/A-line.
• Shoes : nude toe elongates the leg; thin sandals for midi/minis; block heel for long evenings.

Common Mistakes (and How to Avoid Them)

• Mermaid cut too tight : go up 1 size and adjust the waist; add a slit for walking.
• Sequins + complex cut : visual overload; prefer simple line .
• Slipping straps : shorten in alterations, or switch to a more stable V-neckline .
• Hem too long : walk on the dress → hem it with your final heels .
• Misplaced patterns/ruffles : Avoid adding volume exactly where you already have a lot.
