Finding the right size for a formal dress is different than shopping for everyday clothing. At Lady Black Tie, we carry gowns from a wide range of designers, and each designer develops their own sizing standards. That means your formal dress size may be different from the size you typically wear in jeans, tops, or everyday dresses.
The most important step is to choose your size based on your body measurements, not your usual clothing size.
Why Formal Dress Sizes Are Different
Unlike everyday fashion brands, formalwear designers do not follow one universal sizing standard. A size 4 from one designer may fit differently than a size 4 from another.
Many formal gowns are designed with:
- Structured bodices
- Corset construction
- Minimal stretch
- Built-in support
- Couture-inspired silhouettes
These features create a beautiful fit but often require sizing differently than everyday clothing.
How to Measure Yourself
For the most accurate fit, wear the undergarments you plan to wear with your dress and use a soft measuring tape.
Bust
Measure around the fullest part of your bust while keeping the tape level.
Waist
Measure the narrowest part of your natural waist, usually just above your belly button.
Hips
Measure around the fullest part of your hips, approximately 8–10 inches below your waist.
Order Based on Your Largest Measurement
This is the most important sizing tip we can give.
If your measurements fall into multiple sizes, we recommend choosing the size that accommodates your largest measurement. It is much easier for a local tailor to take a dress in than to let one out.
Example:
- Bust: Size 4
- Waist: Size 6
- Hips: Size 8
Recommended Size: 8
Your tailor can customize the fit through the bust and waist for a beautifully tailored look.
Expect Alterations
Alterations are a normal part of formalwear.
Even celebrities, pageant contestants, brides, and models have their gowns professionally tailored before wearing them. Hemming, taking in the waist, adjusting straps, or refining the bodice are all common alterations that help create a custom fit.
Do Formal Dresses Run Small?
Many formal dresses fit differently than everyday clothing.
Depending on the designer and silhouette, you may need to order one or more sizes above your typical street size. This is completely normal and does not mean the dress is mislabeled.
Always rely on your measurements and the designer's size chart instead of your everyday clothing size.
Stretch vs. Structured Dresses
Not all gowns fit the same.
Structured Dresses
- Corset bodices
- Mikado
- Jacquard
- Brocade
- Heavy satin
- Minimal stretch
These styles should fit your measurements closely.
Stretch Dresses
- Jersey
- Stretch satin
- Stretch mesh
- Spandex blends
These fabrics offer more flexibility and can provide a closer fit.
Common Questions
I'm between sizes. Which size should I choose?

Formal gowns have limited seam allowance, making them difficult to let out if they are too small.
