Find Your Perfect Fit

One of the reasons we love the KMbridal® Infinity Dress is its flexibility.

The long convertible straps allow the dress to be wrapped, tied, and adjusted in many different ways, creating a comfortable and flattering fit for a wide range of body shapes.

However, One Size does not mean every size.

Please use the guide below to choose between One Size and One Size Plus before placing your order.

Infinity Dress Size Chart

Short / Knee-Length Infinity Dress

Dress Length

Floor-Length Infinity Dress

Approx. 43 inches / 109 cm

The length is measured from the waistline to the bottom hem.

Knee-Length Infinity Dress

Approx. 25 inches / 64 cm

The length is measured from the waistline to the bottom hem.

Please note that the final position of the hem will vary depending on your height, body proportions, how high you wear the waistband, and your shoes.

How to Choose Your Size

Choose ONE SIZE if you normally wear:

US 0–18 / S–2XL

This is our standard Infinity Dress size and is designed to accommodate a wide range of body shapes through the adjustable wrap construction.

Choose ONE SIZE PLUS if you normally wear:

US 18–24 / XL–4XL

The Plus version provides additional room and fabric for a more comfortable fit while maintaining the same convertible styling possibilities.

Between One Size & Plus?

If you normally wear around US 18 and are deciding between One Size and One Size Plus, consider your measurements and preferred fit.

Choose One Size if you generally wear US 18 comfortably and prefer a closer fit.

Choose One Size Plus if you prefer additional coverage, more wrapping room, or a more relaxed and comfortable fit.

When in doubt, we generally recommend choosing the roomier option.

Because Infinity Dresses are designed to wrap and adjust around the body, having a little extra fabric usually gives you more styling flexibility.

How to Measure

For the best fit, take your measurements while wearing lightweight clothing or undergarments.

Use a soft measuring tape and keep it comfortably fitted against your body without pulling it too tight.

1. Bust

Measure around the fullest part of your bust.

Keep the measuring tape level across your back.

2. Waist

Measure around your natural waistline, usually the narrowest part of your torso.

Don't pull the measuring tape too tightly.

3. Hips

Stand naturally with your feet together and measure around the fullest part of your hips and seat.

4. Height

Measure from the top of your head to the floor while standing straight without shoes.

Height is particularly important when considering the length of a floor-length Infinity Dress.

What About the Bust?

Unlike a traditional fitted bridesmaid dress, the KMbridal® Infinity Dress uses long convertible straps to create the upper portion of the dress.

This gives you much more flexibility around the bust than a conventional fixed-bodice dress.

The straps can be wrapped and adjusted to create different levels of:

Coverage · Support · Neckline · Back Coverage

Women with a fuller bust may prefer styles that provide wider strap coverage or additional support.

Depending on your preferred styling method, you may also choose to wear a bandeau, strapless bra, adhesive bra, or other suitable undergarment.

What About the Waist?

The Infinity Dress is designed with flexibility around the waist, but choosing the correct size range is still important.

The long straps wrap around the waist and can be adjusted according to your body shape and preferred fit.

If you're near the upper end of the One Size range or prefer additional wrapping coverage, One Size Plus may be the better choice.

What About the Hips?

The flowing skirt construction makes Infinity Dresses more forgiving through the hip area than many traditional fitted bridesmaid dresses.

However, body proportions vary from person to person.

If your hip measurement typically places you in a larger clothing size than your waist or bust measurement, we recommend choosing the size that provides you with the most comfortable overall fit.

Choosing the Right Length

Floor Length

Our floor-length Infinity Dress has an approximate waist-to-hem length of 43" / 109 cm.

The same dress may appear longer or shorter depending on your height.

Petite Bridesmaids

If you're petite, the dress may require hemming depending on your height and shoes.

Because of the simple flowing skirt construction, professional alterations can usually adjust the length if needed.

Taller Bridesmaids

If you're taller than average, please review the 43" / 109 cm waist-to-hem measurement carefully before ordering.

If you are unsure whether the dress will be long enough for you, contact us before purchasing.

Wearing Heels?

Remember to consider your wedding shoes when evaluating dress length.

A dress that reaches the floor when barefoot may sit noticeably higher when worn with heels.

Perfect for Bridal Parties

Different bridesmaids don't need identical body types to wear the same dress beautifully.

That's the idea behind the Infinity Dress.

Your bridal party can wear:

The same color.
The same fabric.
The same dress.
Different necklines and wrapping styles.

Each bridesmaid can adjust her dress to create a look that feels comfortable and flattering for her body.
