How to Choose the Right Bridesmaid Dress Size - A Practical Guide for Brides

Date: 26 Aug 2025

Choosing bridesmaid dresses is one of the most exciting tasks for any bride. These dresses are not just elegant outfits – they symbolize the friendship and support your bridesmaids give you on your big day. That’s why it’s important that they look harmonious together, while also making each bridesmaid feel comfortable and confident.

When it comes to dresses, we often think about color and style, but the right size is just as important. Your bridesmaids will be with you all day – during the photo session, the ceremony, and dancing late into the night. Their dresses need to allow freedom of movement, elegance, and self-confidence.

This guide will show you how to choose the correct size for bridesmaid dresses – from taking accurate measurements to avoiding common mistakes.

Why the Right Size Matters

Every bride dreams of perfect wedding photos where everything looks flawless. But even the most beautiful dress can look unflattering if it’s the wrong size.

Dresses that are too small create discomfort and limit movement.
Dresses that are too large look shapeless and often require emergency alterations.
The right size highlights each bridesmaid’s best features and balances style with comfort.

Who Decides on the Bridesmaid Dress Size

Usually, the bride chooses the model and color of the dresses to create a unified look. But size is individual, and it’s important to involve your bridesmaids in the process.

Practical tip:
Send clear instructions on which measurements are needed and ask your bridesmaids to take them carefully (ideally with someone’s help). Then compare the results with the brand’s size chart.

How to Ask Your Bridesmaids for Measurements

To avoid mistakes, provide a simple list of required measurements:

Bust – around the fullest part of the chest.
Waist – the narrowest part of the torso.
Hips – the widest part, across the buttocks.
Length – if the dresses are floor-length, this should be taken with the shoes they will wear.

You can even organize a measurement day – a fun way to collect everyone’s numbers together while enjoying the wedding preparations.

Size Charts – EU, UK, US

Many bridesmaid dress suppliers use different sizing systems:

EU sizes – 36, 38, 40, 42.
UK sizes – 8, 10, 12, 14.
US sizes – 2, 4, 6, 8.

Always check the specific brand’s size chart – there is no universal standard.

What to Do If a Bridesmaid Falls Between Two Sizes

This is very common! A bridesmaid may have bust measurements for one size and hips for another.

Golden rule: always size up.
It’s easier to take a dress in than to let it out.

How Dress Styles Affect the Fit

The cut of the dress determines how forgiving it is on different body types:

A-line – universally flattering, suits every body shape. The safest choice.
Empire waist – emphasizes the bust, flows loosely over hips and tummy. Great for a variety of figures.
Mermaid – fitted to the knees before flaring out. Requires very precise measurements.
Sheath (straight) – sleek and elegant, but can be less forgiving for movement.

How Fabric Influences Fit

Fabric choice can change how a dress feels, even in the correct size:

Chiffon and tulle – light and flowy, easy to move in.
Satin – structured and elegant, requires accurate sizing.
Lace – often has some stretch but shows the body’s natural lines.

Alterations – a Normal Part of the Process

Almost every bridesmaid dress requires small alterations:

Shortening the hem based on shoe height.
Taking in the waist or bust.
Adjusting straps or sleeves.

Tip:
Leave at least 2–3 weeks before the wedding for final fittings and alterations.

Common Mistakes Brides Make with Bridesmaid Dress Sizes

Ordering only based on the label size without taking measurements.
Choosing dresses that are too small, hoping bridesmaids will lose weight.
Not leaving enough time for alterations.
Forgetting about comfort – bridesmaids will walk, pose for photos, and dance.
Insisting on a single cut that doesn’t flatter all body types.

Tips for Brides

Collect measurements early.
Order the dresses at least 3–4 months in advance.
Pick a cut that works for everyone.
If you want identical dresses – A-line is the safest choice.
If you want variety – choose different cuts in the same color palette.

Conclusion

Choosing the right bridesmaid dress size is just as important as picking the style or color. It’s a balance between your dream wedding vision and your bridesmaids’ comfort. With accurate measurements, the right cut, and time for alterations, you’ll ensure your bridesmaids look and feel amazing.

Remember: when bridesmaids are confident and happy in their dresses, the entire wedding looks more harmonious.
