What Is Hollow to Hem? Dress Measurement Definition & How to Measure It

Updated October 2026 by the MsDressly editorial team.

What hollow to hem means

The hollow to hem measurement answers one simple question: where will this dress actually end on me? It's taken by placing the end of a measuring tape in the "hollow" — the small dip at the center of your collarbones, right where a pendant necklace naturally rests — and letting the tape fall straight down the front of your body to the point where the dress hem will sit.

Unlike your overall height, which includes your head and neck, hollow to hem measures only the vertical distance your dress covers, from neckline to bottom edge. That's why two people of the same height can need very different hollow to hem numbers if one has a longer torso or plans to wear heels.

Why hollow to hem matters more than your height

Size charts often list a model's height, but height alone can't tell you how a dress will fall. A petite woman with a long torso and a tall woman with a short torso might both stand 5'6" — yet the same maxi dress will pool on the floor for one and hover awkwardly above the ankle for the other.

Hollow to hem removes the guesswork. When a product page lists this measurement, you can compare it directly against your own tape measurement while wearing the shoes you plan to wear. If the dress's hollow to hem is 58 inches and yours (in heels) is 56, you can expect a small, elegant train of fabric at the floor. For guidance tailored to shorter frames, browse the maxi dresses for petite women collection, where proportions are cut to flatter.

How to measure hollow to hem at home

• Wear your shoes. Stand in the heel height you plan to wear with the dress — this changes the number significantly.
• Find the hollow. Locate the dip between your collarbones at the base of your neck. This is your starting point.
• Stand tall and straight. Keep your posture natural, shoulders relaxed, and look straight ahead — not down at the tape, which tilts the measurement.
• Run the tape vertically. Let the tape fall straight down over the fullest part of your bust and continue to where you want the hem to hit (ankle, floor, or with a small puddle).
• Have a friend help if possible. A second set of eyes keeps the tape vertical and the reading accurate.

Hollow to hem vs. other dress measurements

Hollow to hem is frequently confused with two other numbers:

• Full length / height: Your total standing height, head to toe. This includes the head and neck, so it's always greater than your hollow to hem.
• Waist to hem: Measured from your natural waistline down. This is used for skirts and high-waisted dresses, and ignores everything above the waist.

Hollow to hem is the most complete "length" number for a one-piece dress because it spans the entire garment from neckline to bottom edge in one straight line.

Hollow to hem by dress type

Different silhouettes aim for different hollow to hem targets:

• Mini: roughly 32–36 inches on most wearers, hitting mid-thigh.
• Knee-length: around 38–42 inches, landing just above or at the knee.
• Midi: approximately 44–50 inches, falling between the knee and ankle. See the midi and maxi skirts collection for pieces in this range.
• Maxi / floor-length: typically 56–62 inches, brushing the floor. Anything longer is designed for heels or a slight puddle effect.

Always compare the number to your own measurement rather than assuming a label like "maxi" guarantees floor length.

Hollow to hem in wedding and formal wear

Hollow to hem is most critical for formal dresses, where a hem that's an inch off can ruin a look. Wedding guest dresses, bridesmaid gowns, and mother-of-the-bride styles are routinely ordered by hollow to hem so the hem skims the shoe exactly. When shopping satin A-lines, one-shoulder gowns, or dresses with hollow-out details, check the size chart's length column before ordering — especially if you're between standard heights.

Special hem styles and how length works with them

Some hems deliberately break the "straight across" rule, which changes how you should read the measurement:

• Hanky hem: A handkerchief hem has pointed, handkerchief-like corners at varying lengths. Use hollow to hem at the shortest point so you know the highest the dress will ride.
• Dip hem (high-low): Shorter in front, longer in back. Check both the front and back hollow to hem numbers — the difference between them is the "dip."
• Asymmetrical hem: Angled or one-sided. Measure on the side where the hem sits lowest for the most conservative length estimate.

Our asymmetrical hem styles show how a diagonal edge changes where the fabric falls on each leg.

Common hollow to hem mistakes to avoid

• Measuring barefoot when you'll wear heels — add your heel height to the number.
• Looking down while measuring, which shortens the reading by up to an inch.
• Measuring over bulky clothing. Use fitted clothing or measure in light layers.
• Ignoring the neckline. A high neckline and a plunging V on the same-length dress will land differently at the hem.
• Skipping the size chart. Brands vary, so always compare your number to the specific garment's listed hollow to hem.

How to shop using hollow to hem

Start with your own measurement in the shoes you'll wear. Then, on each product page, locate the length specification in the size chart — often labeled "hollow to hem," "dress length," or "length from shoulder." Subtract your number from the garment's number: a difference of +1 to +2 inches means the fabric will pool slightly at the floor (ideal for gowns), while -1 to -2 inches means the hem will hover just above the ground.

When in doubt between two sizes, choose by bust and waist fit first, then treat length as a tailoring question — hemming a dress shorter is straightforward, but adding length is rarely possible. MsDressly offers free shipping when buying 2 or more items, or on orders over US$80, so ordering two sizes to compare fit is cost-effective; just note that return shipping is paid by the customer.
