How to measure bra size yourself

Tips to help you get your band and cup measurements just right. We recommend checking every six months to make sure you're always wearing the right size.

3 easy steps to measuring bra size

  1. Measure your band. Wear a lightly lined (non-push-up) bra so your breasts are as close to natural as possible. Wrap a measuring tape directly under your breasts. Make sure it’s directly parallel with the bottom of the bra band.
  2. Now measure your bust. Place the tape at the fullest part of your bust. Make sure it’s parallel to your band again.
  3. Subtract the band size from your bust size to find the right cup size. Every inch equals one cup size up. Check our chart below.

Bra Fit FAQs: Learn How To Measure Bra Size

How do bra sizes work?

Bra sizes combine ribcage and bust measurements. The band size is determined by the ribcage, while cup size results from the difference between ribcage and bust measurements. A well-fitted bra enhances posture, prevents discomfort, and boosts confidence, contributing to overall physical and emotional well-being. You can use our guide to learn how to measure bra size or visit a Lane Bryant store near you for a free bra fitting.

How is a bra supposed to fit?

When measuring bra size, it’s important to first understand how a bra should fit. A properly fitting bra should provide comfort, support, and enhance your natural shape. The band should be snug but not tight, sitting parallel to the ground. The underwire, if present, should lie flat against the ribcage without digging in. Cups should fully encase the breasts, with no spillage or gaps. Straps should stay in place without digging into the shoulders. A well-fitted bra contributes to good posture and overall comfort. If any part feels uncomfortable or doesn't align with these guidelines, it's a sign that adjustments in size or style may be needed.

How should a bra cut fit?

A bra cut, referring to the style or design of the bra cup, should fit in a way that complements your breast shape and enhances your silhouette. Here are some general guidelines for measuring bra size when considering different bra cuts:

Full-Cup: This style provides full coverage, and the cups should fully encase the breasts without spillage. The center gore (the part between the cups) should lie flat against the chest.

Balconette or Demi-Cup: These styles have lower-cut cups that reveal more of the upper part of the breasts. The cups should still fully contain the breast tissue, and there should be no bulging or gaps.

Plunge: Plunge bras have a deep V-shape in the center. The center gore should lie flat, and the cups should support the breasts without causing spillage.

Push-up: If you're wearing a push-up bra, the padding or underwire should lift and enhance your cleavage, but the cups should still fully cover the breasts without causing discomfort.

Sports Bra: The sports bra should provide strong support during physical activities. It should compress the breasts slightly to minimize movement but not be so tight that it causes discomfort or restricts breathing.

T-shirt Bra: A T-shirt bra should fit smoothly with contoured cups, no spillage or gaps, a flat center gore, and a comfortable, supportive band.

Ultimately, the key is to ensure that the bra cut complements your body shape, provides the desired level of coverage and support, and feels comfortable throughout the day.

How many bras should I have?

As a general guideline, it's recommended to have at least 7 bras, one for everyday of the week. However, the number of bras you should have depends on your lifestyle, preferences, and laundry routine.

  • Everyday Bras: 3-5 bras for daily wear, allowing you to rotate them and extend their lifespan.

  • Sports Bras: 2-3 sports bras for your workout routines, ensuring proper support during physical activities.

  • Specialty Bras: Consider adding a strapless bra, a bra with a different cut (like a balconette or plunge) for specific outfits, and a comfortable bralette for lounging.

  • Nursing Bras: If applicable, nursing bras are essential for breastfeeding mothers, and having 2-3 can be practical.

  • Comfort Bras: Include a couple of comfortable, wire-free bras for days when you prioritize comfort over structure.

Remember that bras wear out over time, so regularly assess their condition and replace them as needed. Adjust the number based on your personal preferences and how often you do laundry. Having a well-curated collection ensures you have the right bra for any occasion while maintaining the longevity of each piece.

How should I wash bras?

To prolong the life of your bras and maintain their shape, follow these washing tips:

  1. Hand Wash Preferred: Hand washing is the gentlest method. Fill a basin with lukewarm water and add a small amount of mild detergent.

  2. Use a Delicate Detergent: Choose a detergent specifically formulated for delicates or lingerie. Avoid using harsh chemicals that can damage the fabric and elastic.

  3. Gently Rub Fabric: Gently rub the fabric between your fingers, paying attention to areas like the underwire channels and straps. Do not twist or wring.

  4. Rinse Thoroughly: Rinse the bras thoroughly with cool water until all detergent is removed. Press out excess water, but again, avoid wringing.

  5. Press Out Excess Water: After rinsing, press out excess water without wringing or twisting.

  6. Dry Flat: Lay bras flat on a clean, dry towel to air dry. Reshape the cups and straps to maintain their form.

  7. Avoid Hanging: Hanging bras by the straps can cause them to stretch. If you must hang them, do so by the center gore.

  8. Fasten Hooks: Before washing, fasten the hooks to prevent snagging on other garments.

  9. Use a Mesh Bag (Optional): If using a washing machine, place bras in a mesh lingerie bag to protect them from tangling with other items.

Remember to check the care instructions on the bra's tag, as some bras may be machine washable in a mesh bag on a delicate cycle. Following these tips helps to preserve the elasticity and shape of your bras, ensuring they remain comfortable and supportive.
