How to Size a Bra: A Comprehensive Guide
Finding the perfect bra can feel like searching for a needle in a haystack. With varying styles, materials, and sizes, it can be overwhelming to know where to begin. However, knowing how to size a bra correctly is the first step toward comfort and support. In this guide, we will explore the methods for finding your ideal bra size, common mistakes to avoid, and tips for ensuring a perfect fit.
Understanding Bra Sizes
Before diving into the sizing process, it’s essential to understand how bra sizes work. A bra size consists of two components: the band size and the cup size.
- Band Size: This is the number in your bra size (e.g., 34, 36, 38). It refers to the measurement around your rib cage, just under your bust.
- Cup Size: This is the letter in your bra size (e.g., A, B, C, D). It indicates the volume of the bust and is determined by the difference between your bust measurement and your band size.
- Rib cage measurement: 32 inches (even) + 4 = 36 (band size)
- Bust measurement: 38 inches
- Difference: 38 – 36 = 2 inches (B cup)
- A soft measuring tape
- A mirror
- A notepad and pen to record your measurements
- A well-fitting, non-padded bra (optional)
- Subtract your band size from your bust size. Use the difference to determine your cup size based on the following scale:
- Check the Band: The band should be snug but not uncomfortable. It should sit horizontally across your back.
- Assess the Cups: Your breasts should fill the cups without spilling over. If there’s gaping, the cups may be too large.
- Adjust the Straps: Straps should be adjustable and provide support without digging into your shoulders.
- Move Around: Raise your arms, bend over, and move around to ensure the bra stays in place and feels comfortable.
- Ignoring the Band Size: Many women focus solely on cup size and overlook the importance of the band size. A properly fitting band provides most of the support.
- Wearing an Old Bra: Over time, bras lose their elasticity. If you’ve been wearing the same bra for years, it might be time for a new one.
- Not Trying Different Styles: Different styles (e.g., underwire, wireless, sports bras) can fit differently. Always try various styles to find the most comfortable one.
- Assuming a Size is Universal: Sizes can vary between brands. Always check the size chart for each brand, as a 36B in one brand may not fit the same in another.
- Rotate Your Bras: Don’t wear the same bra every day. Rotating between bras helps maintain elasticity.
- Wash with Care: Hand wash your bras in cold water and air dry them to extend their lifespan.
- Store Properly: Avoid folding bras; instead, lay them flat or stack them in a way that maintains their shape.
- Weight loss or gain
- Pregnancy or breastfeeding
- Changes in hormone levels (e.g., menopause)
- Discomfort with your current bras
- Daily Wear: T-shirt bras or wireless bras offer comfort.
- Sports: A good sports bra provides support during physical activities.
- Special Occasions: Strapless or push-up bras can enhance your silhouette.
The Bra Size Formula
The general formula for determining your bra size is:
1. Band Size: Measure around your rib cage, under your bust. Add 4 inches if the measurement is even or 5 inches if it’s odd.
2. Cup Size: Measure around the fullest part of your bust. Subtract your band size from this measurement. Use the difference to determine your cup size.
Example
So, your bra size would be 36B.
How to Measure for Bra Size
Step 1: Gather Your Tools
Before you begin measuring, gather the following:
Step 2: Measure Your Band Size
1. Stand Up Straight: Keep your back straight and your arms relaxed at your sides.
2. Wrap the Measuring Tape: Place the tape around your rib cage, just under your bust. Ensure it’s snug but not too tight.
3. Record the Measurement: Note the measurement in inches. If it’s even, add 4 inches; if it’s odd, add 5 inches to get your band size.
Step 3: Measure Your Bust Size
1. Position the Tape: Wrap the measuring tape around the fullest part of your bust. Make sure it’s parallel to the ground and not too tight.
2. Record the Measurement: Note this measurement in inches.
Step 4: Calculate Your Cup Size
| Difference (inches) | Cup Size |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
| 5 | DD/E |
