How to Measure Yourself for a Perfect Bralette Fit

Quick answer

Measure your underbust snugly and your full bust at the fullest point while wearing an unlined bra, then use those two numbers to choose a bralette size. For wireless styles, the underbust measurement is the most important because it determines whether the band stays put; the bust measurement tells you whether the cups have enough room. Always check the brand's specific size chart before ordering.

A bralette should feel like a second skin, not a compromise. Unlike underwired bras, most bralettes rely on a snug band and stretch fabrics to stay in place, so getting the measurements right is the difference between all-day comfort and constant adjusting.

This guide walks you through how to measure for a bralette at home in five steps, with the common mistakes to avoid at each stage. You will also learn how to translate your numbers into a size for wireless styles, including the bralettes at Angela Friedman.

Before you start: what you need

You do not need a professional fitting to get accurate numbers. A soft measuring tape, a mirror, and a few minutes are enough. Wear an unlined or lightly lined bra so your natural shape is visible, and stand in front of a mirror so you can keep the tape level. If you do not have a flexible tape, use a piece of string and measure it against a ruler afterward.

Take your measurements in inches or centimeters, but stay consistent. Write both numbers down before you look at any size chart, because rounding too early can push you into the wrong size. The goal is a starting point, not a perfect match on the first try.

• Wear an unlined bra, not a push-up or sports bra, for the most accurate bust measurement.
• Keep the tape parallel to the floor; a tilted tape adds inches that are not there.

Step 1: Measure your underbust

Wrap the tape around your ribcage, directly under your bust where the band of a bra would sit. Keep it snug but not tight enough to compress your skin. Breathe normally and exhale before you read the number. This measurement determines the band size, which is the foundation of bralette fit.

For wireless bralettes, the underbust is often the only measurement you need because the fabric stretches to accommodate the bust. If your underbust falls between two sizes, size up for comfort unless the brand specifies a very stretchy fabric.

• Checkpoint: the tape should stay level all the way around and not dig in.
• Mistake to avoid: measuring over a padded bra or thick clothing, which adds bulk.

Step 2: Measure your full bust

Wrap the tape around the fullest part of your bust, usually across the nipple line. Keep the tape level and snug, but do not pull it tight enough to flatten your natural shape. Stand straight with your arms at your sides and look in the mirror to confirm the tape is not twisted or sagging at the back.

This number tells you how much room the cups need. In a triangle bralette, the fabric should cover your bust without cutting in or gaping. If your bust measurement is much larger than your underbust, look for styles with adjustable straps and a wider band for extra support.

• Checkpoint: the tape should touch your bust lightly, not compress it.
• Mistake to avoid: measuring while wearing a push-up bra, which changes your natural shape.

Step 3: Find your size on the brand's chart

Every brand sizes bralettes differently, so always use the specific size chart for the style you are considering. Compare your underbust and bust measurements to the chart's ranges, not just a single number. If you fall between sizes, choose the larger size for wireless styles, because a band that is too tight is uncomfortable and a band that is too loose will ride up.

For example, the Lydia bralette is a longline wireless style with stretch silk lining the cups, which gives some flexibility in the bust. The Amandine bralette uses a classic triangle cut with imported French lace and offers less stretch, so your bust measurement matters more for that shape.

• Checkpoint: your underbust should match the band range, and your bust should fall within the cup range.
• Mistake to avoid: assuming your T-shirt bra size is your bralette size; they are often different.

Step 4: Check the band and cup fit on your body

Once you receive your bralette, put it on and fasten it on the loosest hook if it has one. The band should feel snug but not painful, and it should stay in place when you lift your arms. The cups should cover your bust without digging into your skin or leaving empty space at the top. If the band rides up, it is too loose; if it leaves red marks, it is too tight.

For wireless styles, a little stretch is normal, but the bralette should not shift when you move. Adjust the straps so they sit flat on your shoulders without pulling. If the straps dig in, you may need a larger band size rather than a longer strap.

• Checkpoint: you should be able to fit two fingers under the band comfortably.
• Mistake to avoid: judging fit by the straps alone; the band does most of the work.

Step 5: Test the fit with movement

Wear the bralette for 15 minutes around the house before deciding. Bend forward, reach overhead, and sit down to see how the band and cups behave. A well-fitting bralette stays in place with minimal adjustment. If you find yourself pulling it down or up, the size or style is not right for your shape.

If the band is comfortable but the cups gap, try a different style with more coverage or adjust the straps. If the band is too tight but the cups fit, go up a band size. Angela Friedman bralettes come in specific sizes, so use your measurements and the fit test together to choose confidently.

• Checkpoint: after 15 minutes, you should forget you are wearing it.
• Mistake to avoid: keeping a bralette that needs constant adjustment; it will not improve with wear.

Your five-step measuring routine

1. Measure your underbust: Wrap a soft tape snugly around your ribcage directly under your bust, keeping it level and exhaling before you read the number. This is your band size; if between sizes, size up for wireless bralettes.
2. Measure your full bust: Wrap the tape around the fullest part of your bust, keeping it level and snug without compressing your shape. This tells you how much cup room you need; do not measure over a padded bra.
3. Check the brand's size chart: Compare both measurements to the specific chart for the bralette you want, choosing the larger size if you fall between ranges. Every brand sizes differently; never assume your usual bra size applies.
4. Try it on and check the band: Fasten the bralette and ensure the band is snug but not tight, stays in place when you lift your arms, and does not leave red marks. The band should do the work; if it rides up, it is too loose.
5. Test with movement: Wear the bralette for 15 minutes, bending and reaching to see if it stays comfortable and in place without adjustment. If you need to keep adjusting it, the size or style is not right.

Bralette styles to consider

• Lydia bralette: Crafted in sheer navy tulle and real silk, this longline wireless bra is adorned with neon embroidery in brilliant pink and orange hues, with stretch silk lining the cups for full coverage and softness. The longline shape and stretch silk lining offer more coverage and a flexible fit, making it a good choice if you are between sizes or prefer a wireless style that stays put.
• Amandine bralette: The classic triangle cut makes this bralette ideal for both everyday indulgences and special occasions, featuring cups in imported French lace with soft beige lining. The triangle cut provides less coverage than a longline style, so your bust measurement is especially important to ensure the cups fit without gaping.

Measuring yourself for a bralette takes only a few minutes and saves you from the discomfort of a poor fit. Use your underbust and bust measurements as a starting point, check the brand's size chart, and always test the fit with movement. With the right numbers and a little patience, you can find a bralette that feels as good as it looks.
