Step-by-Step Guide to Finding Your Perfect Bra Size

The first step in finding your ideal bra size is to know how to properly measure yourself. You can do this at home with just a soft measuring tape. Here's a simple process to get started:

1. Measure Your Band Size

• Step 1: Stand in front of a mirror, wear a well-fitting bra (or no bra) to ensure accuracy.
• Step 2: Wrap the measuring tape around your ribcage, right under your bust.
• Step 3: Keep the tape snug, but not tight. Take a deep breath to ensure you’re not pulling the tape too tightly.
• Step 4: Round to the nearest whole number. If it’s an odd number, add 1 inch to get your band size.

Example: If your underbust measurement is 30 inches, your band size will be 31 (since 30 is an odd number, we add 1).

2. Measure Your Bust Size

• Step 1: Stand straight with your arms relaxed at your sides.
• Step 2: Wrap the measuring tape around the fullest part of your bust, ensuring the tape is level across your back.
• Step 3: Make sure the tape is snug but not tight, and keep it horizontal all the way around.
• Step 4: Again, round to the nearest whole number.

Example: If your bust measurement is 37 inches, note this down.

3. Calculate Your Cup Size

Now that you have both measurements, it's time to calculate your cup size. To do this, subtract your band size (from Step 1) from your bust measurement (from Step 2).

• Example: If your band size is 31 inches and your bust size is 37 inches, the difference is 6 inches. Use the chart below to determine your cup size:

Difference (in inches)	Cup Size
1 inch	A Cup
2 inches	B Cup
3 inches	C Cup
4 inches	D Cup
5 inches	DD/E Cup
6 inches	DDD/F Cup

In this example, a 6-inch difference corresponds to a D Cup.

4. Your Perfect Bra Size

Now, combine your band size and cup size. Using the example above, your perfect bra size would be 31D.

Top FAQs About Finding Your Perfect Bra Size

Q1: How often should I get measured for a new bra?

It's recommended to get measured at least once a year, as your body can change due to weight fluctuations, pregnancy, or hormonal changes. Additionally, always measure yourself before purchasing a new bra to ensure it still fits properly.

Q2: Why does my bra ride up in the back?

If your bra rides up in the back, your band size might be too big. The band should stay level across your back, providing the majority of the support. If it moves up, try a smaller band size.

Q3: Should I size up or down for a fuller cup?

If you find that your cups are overflowing or your breasts feel squeezed, try going up a cup size. If there’s excess space in the cup, go down a cup size. A properly fitted cup will fully encase the breast without gaping or spilling.

Q4: How tight should my bra band be?

Your band should be snug but comfortable. It should lie flat against your skin, with only a small amount of room between the band and your ribcage. Avoid overly tight bands as they can lead to discomfort or poor circulation.

Q5: Can I wear a bra without underwire?

Yes, you can! Many women prefer non-underwired bras for comfort, especially if they have smaller busts. Wireless bras come in various styles and offer both support and comfort, although they may not provide the same level of lift as underwired bras.

Q6: What if I’m between sizes?

If you're between sizes, it’s usually better to go with the larger band size and adjust the cup size. For example, if you’re a 34B but the band feels tight, try a 36A instead of squeezing into the smaller band.

Q7: How do I know if my bra is the right fit?

A properly fitted bra will feel snug around your ribcage, support your breasts, and not cause any discomfort. Your straps should rest comfortably on your shoulders without digging in, and the cups should hold your breasts without spilling over or gaping.
