To measure yourself for a dress online, use a soft measuring tape and record your bust, natural waist, hips, and—when relevant—hollow-to-floor length and height. Compare those body measurements with the size chart for the specific dress rather than relying only on your usual letter size. Measure over fitted clothing or undergarments, keep the tape level, and do not pull it so tight that it compresses the body.
Accurate measurements are especially important for fitted bandage dresses, evening gowns, structured dresses, and formalwear that may have less room for error.
What you need
- A soft fabric measuring tape.
- A mirror, or ideally someone who can help.
- Fitted clothing or the undergarments you plan to wear.
- A notes app or paper to record each measurement.
- The size chart for the exact product you are considering.
How to measure your bust
Wrap the tape around the fullest part of your bust, keeping it parallel to the floor across your back. Stand naturally and keep the tape comfortably snug rather than tight. Do not inhale dramatically or hold your breath.
How to measure your natural waist
Your natural waist is typically the narrowest point of your torso, often above the belly button and below the rib cage. Bend gently to one side if you are unsure; the crease that forms helps identify the natural waist. Measure without pulling the tape inward.
How to measure your hips
Stand with your feet relatively close together and wrap the tape around the fullest part of your hips and seat. Use a mirror to check that the tape is level all the way around.
How to measure for a long evening gown
For floor-length dresses, the length measurement can matter as much as bust, waist, and hips. Some size charts use “hollow to floor,” measured from the hollow at the base of the neck down to the floor. Others provide total garment length. Read the product chart carefully because these are not always the same measurement.
If you plan to wear heels, check whether the listed dress length already assumes extra length. Do not simply add heel height unless the brand’s instructions tell you to.
How to choose between two sizes
Start with the measurement that matters most for the garment’s structure. In a fitted non-stretch dress, hip or bust room may determine the best size. In a stretch bandage dress, the fabric may allow more flexibility. When measurements fall across different sizes, consult the product-specific size chart and fabric information rather than assuming every style fits identically.
For fitted options, explore Opulent Empire’s bandage dresses; for formal silhouettes, browse evening dresses.
Common measuring mistakes
- Using a rigid construction tape instead of a soft measuring tape.
- Pulling the tape too tightly.
- Measuring over bulky clothing.
- Letting the tape angle up or down around the body.
- Assuming your usual size is identical across every dress.
- Using garment measurements as though they were body measurements, or vice versa.
Measure twice before ordering
Repeat each measurement at least once. If the numbers differ, measure again. Small errors can matter in a highly fitted dress. It is also useful to measure shortly before ordering rather than relying on numbers recorded many months earlier.
Frequently asked questions
Should I measure with clothes on?
Use fitted clothing or undergarments so bulky fabric does not add inches to the measurement.
How tight should the measuring tape be?
It should sit against the body without compressing it. You should be able to breathe and stand naturally.
What if my bust and hips fall into different sizes?
That is common. Prioritize the area that is least forgiving in the garment and consult the style’s size chart and stretch information.
Can a tailor adjust an evening dress?
Many formal dresses can be altered, but what is possible depends on seams, embellishment, fabric, and construction. If alterations are likely, leave enough time before your event.
Before selecting a style from Opulent Empire’s evening and party dresses, compare your measurements with the product-specific sizing information for the best starting point.
