No tape measure? No problem. Learn how to find your bralette size at home using a ribbon, string, or your best-fitting bra as a guide.
Quick answer
You can find your bralette size without a measuring tape by wrapping a ribbon, string, or charging cable around your ribcage, marking where it meets, and comparing that length to a ruler or your best-fitting bra. If you have neither, start with your usual clothing size and adjust based on how the band and cups feel.
A missing measuring tape should not keep you from ordering a bralette that fits. You already have everything you need at home: a piece of string, a ribbon, or even a phone charging cable. The trick is to measure your ribcage and bust with a flexible item, then convert that length using a ruler or a printable ruler on your phone.
This guide walks you through a no-tape-measure method that works for any bralette, including soft lace styles from Chouchou Intimates. You will also learn how to use a well-fitting bra as a reference and what to check once your bralette arrives.
Step 1: Find a Flexible Measuring Tool
Look for anything flexible and non-stretchy: a ribbon, a piece of yarn, a shoelace, or a charging cable. Avoid elastic bands because they stretch and give a false reading. If you use a ribbon or string, make sure it is long enough to wrap around your ribcage and bust comfortably.
Once you have your tool, keep a ruler, a tape measure, or a ruler app nearby. You will measure the marked length against it. If you do not have a ruler, you can use a standard sheet of paper (8.5 by 11 inches) as a rough guide, but a ruler gives a more accurate number.
- Checkpoint: Your tool should not stretch when you pull it gently. If it does, choose something else.
Step 2: Measure Your Ribcage
Wrap your flexible tool around your ribcage, directly under your bust. Keep it snug but not tight, and make sure it is level all the way around. Pinch or mark the spot where the tool meets its starting point. This is your ribcage measurement.
Lay the tool flat next to a ruler and note the length in inches. If you are between whole numbers, round up to the nearest half inch. This number helps you find your band size, which is the foundation of bralette fit.
- Common mistake: Measuring over a thick shirt or padded bra. Measure against bare skin or a thin, unpadded layer for accuracy.
Step 3: Measure Your Bust
Wrap the same tool around the fullest part of your bust, usually across the nipple line. Keep it level and snug, but do not compress your breast tissue. Mark where the tool meets. This is your bust measurement.
Measure this length against your ruler. The difference between your bust and ribcage measurements helps determine your cup size. For bralettes, exact cup sizing is less critical than for underwire bras, but knowing the difference still guides you toward the right fit.
- Checkpoint: If your bust measurement is more than 3 inches larger than your ribcage, you may need a bralette with adjustable straps or a more supportive style.
Step 4: Convert to a Bralette Size
Most bralettes use simple sizing like XS, S, M, L, or a combination like S/M. Use your ribcage measurement to find your band size: 28-30 inches is usually XS, 30-32 is S, 32-34 is M, 34-36 is L, and so on. Then check the bust measurement to decide if you should size up for more coverage.
If you fall between two sizes, consider the fabric. Stretchy lace and mesh, like the Taylor Bralette, will give more, while structured cotton styles may feel snug. When in doubt, size up for comfort, especially if you prefer a relaxed fit.

- Tip: Write down both measurements and your likely size before you shop. It saves time and returns.
Step 5: Use Your Best-Fitting Bra as a Backup
If you already own a bra that fits well, lay it flat and measure the band from end to end, then double that number. That gives you your band size. For the cup, measure the fullest part of the bra cup across the front. Compare these numbers to your body measurements to confirm your size.
This method works best with an unlined or lightly lined bra. A heavily padded bra will distort the cup measurement. Use it as a cross-check, not your only source.
- Checkpoint: If your bra band measurement and ribcage measurement differ by more than 2 inches, remeasure both.
Step 6: Test the Fit When Your Bralette Arrives
Put on your new bralette and check the band first. It should sit snugly around your ribcage without riding up or digging in. You should be able to fit one finger under the band. Next, check the cups: they should cover your breast tissue without gaping or spilling.
Adjust the straps so they stay in place without pulling. Move around, raise your arms, and bend over. A well-fitting bralette stays put and feels comfortable for hours. If it does not, you may need a different size or style.
- Common mistake: Keeping a bralette that feels too tight because you expect it to stretch. If it digs in now, it will only get worse.
Your No-Tape Bralette Sizing Checklist
- Gather a non-stretchy flexible tool: Use a ribbon, string, or charging cable. Avoid elastic. Checkpoint: The tool should not stretch when pulled.
- Measure your ribcage: Wrap snugly under your bust, mark the length, and measure against a ruler. Common mistake: Measuring over thick clothing.
- Measure your bust: Wrap around the fullest part, keep level, and mark the length. Checkpoint: If bust is 3+ inches larger than ribcage, look for adjustable straps.
- Convert to a bralette size: Match ribcage to band size, then adjust for bust and fabric stretch. Tip: Size up if between sizes and prefer a relaxed fit.
- Cross-check with a well-fitting bra: Lay your bra flat, measure the band, and double it. Checkpoint: If numbers differ by 2+ inches, remeasure.
- Test the fit when it arrives: Check band snugness, cup coverage, and strap adjustment. Move around. Common mistake: Keeping a too-tight bralette hoping it will stretch.
Bralettes That Make Sizing Easier
- Gabriela Bralette & French Knicker Set: Gabriela features a soft lace bralette and French knicker, available in warm Buttercup and classic Black, designed to be an everyday favourite. Soft lace has natural give, so it accommodates small size variations and feels comfortable if you are between sizes.
- Georgia Bralette & Thong Set: Georgia is made from 100% organic cotton with rich red velvet bows and delicate scalloped trim, available in blushing pink, white, and black. Cotton has less stretch than lace, so if you are between sizes, consider sizing up for a more comfortable fit.
Finding your bralette size without a measuring tape is simpler than it sounds. With a ribbon and a ruler, you can get accurate measurements and choose a size that feels comfortable from the first wear. Remember that fabric matters: stretch lace forgives, while cotton holds its shape. When in doubt, size up and adjust.
