Introduction

Finding the perfect-fitting lingerie is about more than aesthetics—it’s a foundational confidence boost. Ill-fitting bras can lead to discomfort, poor posture, and even long-term health issues. Whether you’re a lingerie aficionado or new to the lingerie drawer, this ultimate size guide will walk you through everything you need to know to discover your ideal lingerie fit.


1. Why Proper Fit Matters

  • Comfort & Support: The right size ensures optimal support for everyday wear, reducing strain on shoulders and back.
  • Health Benefits: Ill-fitting bras can cause skin irritation, poor circulation, and muscle tension.
  • Boost Confidence: Well-fitted lingerie enhances your natural shape, giving a smoother silhouette under clothing.

2. How to Measure Your Lingerie Size

Band Measurement

  • Wear a non-padded bra.
  • Wrap a soft measuring tape snugly around your ribcage, just under the bust.
  • Exhale and record the measurement in inches (e.g., 32, 34, 36).

Bust Measurement

  • Measure around the fullest part of the bust, keeping the tape parallel to the floor.
  • Ensure the tape is neither too tight nor too loose.

Calculating Cup Size

  • Subtract the band measurement from the bust measurement.
  • Each inch difference corresponds to one cup size (1″ = A, 2″ = B, etc.).
  • Example: Bust 36″ – Band 34″ = 2″ → Size 34B.

Pro Tip: Re-measure every 6–12 months, as body changes can affect fit.


3. Understanding Lingerie Size Charts

  • International Variations: US, UK, EU, and FR sizing differ—always check the brand’s size chart.
  • Sister Sizes: If your exact size is unavailable, sister sizes can help. For instance, if 34B is too tight in the band, try 36A.
US Size UK Size EU Size FR Size
32A 32A 70A 85A
34B 34B 75B 90B
36C 36C 80C 95C

4. Common Fit Issues & Solutions

Issue Cause Fix
Band rides up Band too big Go down a band size
Straps dig in Straps carrying too much weight Tighten straps or adjust band size
Gaps in cups Cups too large Try a smaller cup or different style
Spillage over cups Cups too small Increase cup size

5. Tips for Trying On and Shopping Online

  • Try Before You Buy: Visit a boutique for a professional fitting when possible.
  • Read Reviews: Look for notes on true-to-size vs. runs small/large.
  • Check Return Policies: Ensure easy exchanges if sizing doesn’t work out.

6. Style Recommendations by Body Shape

  • Full Bust: Look for underwire support, wider straps, and balconette styles.
  • Small Bust: Push-up or padded bras add volume; bralettes can offer a comfortable, minimal look.
  • Athletic Build: Triangle cups and plunge styles help create curves.

7. Frequently Asked Questions (FAQs)

Q: How often should I replace my bra?
A: Every 6–12 months, depending on wear and care.

Q: Can I wear the same size across different brands?
A: Not always. Always consult each brand’s size chart.

Q: What if my measurements fall between sizes?
A: Try sister sizes and different cuts until you find your best match.
