How to Take Your Measurements
Accurate measurements are the foundation of finding the right size. Grab a soft measuring tape and follow these steps. If you do not have a measuring tape, use a string and measure it against a ruler.
- Bust: Measure around the fullest part of your chest, keeping the tape horizontal across your back and under your arms. Do not pull too tight. Wear a non-padded bra or the bra you plan to wear with your dress.
- Waist: Find your natural waistline, the smallest part of your torso, usually about one inch above your belly button. Keep the tape snug but not tight.
- Hips: Stand with feet together and measure around the fullest part of your hips, typically about 7 inches below your natural waist.
- Height: Stand against a wall without shoes. Mark the top of your head and measure from the floor to the mark.
Pro tip: Have someone else take your measurements for the most accurate results. Stand naturally and do not hold your breath.
Understanding Your Body Type
The Fit Finder calculates your body type based on the proportions between your bust, waist, and hips. Here is what each body type means and which silhouettes tend to work best.
Hourglass
Your bust and hips are similar in width with a well-defined waist. You have balanced proportions and natural curves.
Best silhouettes: Mermaid, Trumpet, Fit & Flare, Bodycon
Pear
Your hips are wider than your bust with a defined waist. Your lower body carries more weight than your upper body.
Best silhouettes: A-Line, Ball Gown, Empire Waist, Fit & Flare
Apple
You carry weight in your midsection with a less defined waist. Your bust may be fuller and your legs are often slim.
Best silhouettes: Empire Waist, A-Line, Column with ruching
Rectangle
Your bust, waist, and hips are similar in width. You have a straight, athletic silhouette without dramatic curves.
Best silhouettes: Ball Gown, Fit & Flare, Bodycon, A-Line with embellished waist
Inverted Triangle
Your shoulders and bust are wider than your hips. You have a strong upper body with narrower lower body.
Best silhouettes: Ball Gown, A-Line, styles with full skirts to balance shoulders
Slender
You have a lean, narrow frame throughout. Your proportions are balanced but without dramatic curves.
Best silhouettes: Column, Bodycon, Mermaid, styles with details that add dimension
Prom Dress Silhouettes Explained
Each silhouette creates a different effect. Understanding how they work will help you shop with confidence.
A-Line
The A-Line silhouette is fitted at the bodice and gradually flares out from the waist to the hem, creating an A shape. This is the most universally flattering silhouette because it skims over the hips without clinging. It works for almost every body type and is comfortable to wear all night since it allows freedom of movement. If you are unsure where to start, A-Line is a safe choice.
Mermaid
Mermaid dresses are fitted through the bust, waist, and hips, then flare out dramatically at or below the knee. This silhouette is designed to showcase curves and create a bold, glamorous look. It works best on hourglass and tall figures. Keep in mind that the fitted skirt can restrict movement, so practice walking and sitting before prom night.
Ball Gown
The ball gown features a fitted bodice and a full, voluminous skirt that creates the classic princess silhouette. The dramatic skirt adds volume to the lower body, which helps balance broader shoulders or a larger bust. Ball gowns make a statement and photograph beautifully, but they require more space to move around in.
Trumpet
Trumpet silhouettes are similar to mermaid but flare out higher, around mid-thigh instead of at the knee. This gives you the curve-hugging drama of a mermaid with more ease of movement. It is a great option if you love fitted styles but want to dance without restriction.
Column/Sheath
Column dresses fall straight from the shoulders to the hem with minimal flare. They follow the body’s natural line and create a sleek, modern, elongating effect. This silhouette works well on taller frames and those with rectangle or slender body types. Look for details like slits, interesting necklines, or open backs to add visual interest.
Empire Waist
Empire waist dresses have a raised waistline that sits just below the bust, with the skirt flowing freely from there. This silhouette draws attention to the neckline and shoulders while skimming over the midsection and hips. It is particularly flattering for apple body types and petite frames because it creates the illusion of longer legs.

Fit & Flare
Fit and flare dresses are fitted through the bodice and waist, then flare out at the waist or just below. The flare is less dramatic than a ball gown but more playful than an A-Line. This silhouette emphasizes the waist while adding movement to the skirt. It works well for hourglass, pear, and rectangle body types.
Bodycon/Fitted
Bodycon dresses are form-fitting from top to bottom, following every curve of your body. This is a bold, confident choice that works best on hourglass and slender body types. Look for stretch fabrics like jersey for comfort, and consider strategic ruching to smooth over any areas you want to minimize.
Prom Dress Sizing Tips
Formal dress sizing works differently than everyday clothing. Here is what you need to know to get the right fit.
Prom Sizes Run Differently
Most prom dresses run one to two sizes smaller than your everyday clothing. A girl who wears a size 4 in jeans might need a size 6 or 8 in a prom dress. This is normal. The size is just a number, and what matters is how the dress fits your body.
Size for Your Largest Measurement
If your bust matches a size 6 but your hips match a size 8, order the size 8. It is much easier for a tailor to take in fabric than to let it out. Choose the size that fits your largest measurement, then alter the rest.
Plan for Alterations
Most prom dresses need some alteration. Common adjustments include hemming the length, taking in the waist, or adjusting straps. Budget an extra $50 to $150 for alterations depending on the complexity. Schedule your alterations at least two to three weeks before prom to allow time for multiple fittings if needed.
Important: Order your dress at least 6 to 8 weeks before prom. Popular styles and sizes sell out quickly, and you need time for shipping and alterations.

Frequently Asked Questions
What if my measurements fall between two sizes?
Always size up. A dress that is slightly too big can be altered to fit perfectly. A dress that is too small cannot be let out significantly without compromising the design. When in doubt, go with the larger size and plan for tailoring.
Should I measure myself or have someone else do it?
Having someone else take your measurements is more accurate. It is difficult to keep the tape level and read the numbers while measuring yourself, especially for bust and hips. Ask a parent, friend, or visit a local tailor for professional measurements.
How tight should the measuring tape be?
The tape should be snug against your body but not pulling or compressing your skin. You should be able to slip a finger under the tape. Do not hold your breath or suck in your stomach, as you want your natural measurements.
Does the silhouette affect which size I need?
Yes. For fitted silhouettes like mermaid and bodycon, size based on your largest measurement since the fabric follows your body closely. For A-Line and ball gowns, the bust and waist are more important than hips since the skirt flows freely.
Can I trust the Fit Finder results for ordering online?
The Fit Finder uses Jovani’s official size chart and calculates your size based on your exact measurements. However, we always recommend visiting an authorized Jovani retailer to try on dresses when possible. Use the Fit Finder results as a starting point and reference the size chart on each product page before ordering.
