Your Sister Sizes

If your recommended bra feels too tight or loose in the band, you might find a better fit in a “sister size.” These sizes have the same cup volume but a different band length. For example, if you find a 34F band too loose, try a 32FF.

What is a Panache Bra Size Calculator?

A Panache bra size calculator is a specialized tool designed to determine your correct bra size according to the UK sizing standard used by Panache Lingerie. Unlike generic calculators that might use outdated methods (like adding 4 or 5 inches to the band), this calculator applies the modern “true-to-measurement” system favored by Panache and other leading UK brands. It translates your underbust and overbust measurements into a starting point band and cup size, helping you navigate Panache’s extensive range from B to K cups. This is crucial for anyone seeking the superior support and comfort that a well-fitting Panache bra provides, whether for daily wear or for high-impact sports with the Panache Sport line.

Panache Bra Size Formula and Explanation

Finding your Panache size involves two key calculations: one for the band and one for the cup. Our panache bra size calculator automates this for you.

Formula:

1. Band Size: Underbust Measurement (in inches), rounded to the nearest even number.
2. Cup Volume (Difference): Overbust Measurement (in inches) – Underbust Measurement (in inches).
3. Cup Size: The Cup Volume Difference is mapped to a letter (e.g., 1″ = A, 2″ = B, …, 8″ = FF).

The final size combines the Band Size and Cup Size (e.g., 32FF). This direct measurement method ensures the band provides the majority of the support. For more information on finding the right fit, you can consult a bra fit guide.

Formula Variables

Variable	Meaning	Unit (Auto-Inferred)	Typical Range
Underbust	The measurement around the ribcage directly beneath the bust.	in / cm	26 – 48 in
Overbust	The measurement around the fullest part of the bust.	in / cm	28 – 60 in
Cup Volume Difference	The numerical difference between the Overbust and Underbust.	inches	1 – 15 in

Practical Examples

Example 1: A Common Size

• Inputs: Underbust = 31 inches, Overbust = 39 inches
• Band Calculation: 31 inches rounds up to a 32 band.
• Cup Calculation: 39″ (Overbust) – 31″ (Underbust) = 8″ difference.
• Result: An 8-inch difference corresponds to an FF cup. The final calculated size is 32FF.

Example 2: A Larger Cup Size

• Inputs: Underbust = 94 cm, Overbust = 120 cm
• Unit Conversion: 94cm ≈ 37.0″, 120cm ≈ 47.2″
• Band Calculation: 37.0 inches rounds up to a 38 band.
• Cup Calculation: 47.2″ (Overbust) – 37.0″ (Underbust) = 10.2″ difference.
• Result: A 10-inch difference corresponds to a G or GG cup. The final calculated size is 38G or 38GG.

How to Use This Panache Bra Size Calculator

Using the calculator is simple and takes less than a minute. Follow these steps for an accurate starting size:

1. Select Your Unit: Choose between ‘Inches (in)’ and ‘Centimeters (cm)’ from the dropdown menu.
2. Measure Your Underbust: Using a soft measuring tape, measure around your ribcage right under your bust. Ensure the tape is snug and level all the way around. Enter this number into the ‘Underbust Measurement’ field.
3. Measure Your Overbust: Measure around the fullest point of your bust. The tape should be firm but not tight enough to compress your breast tissue. Enter this into the ‘Overbust Measurement’ field.
4. Interpret Your Results: The calculator will instantly display your calculated Panache UK band and cup size. It also shows intermediate values like your raw cup difference in inches. Use this size as your starting point when shopping. For tips on how a bra should fit, refer to this helpful bra fitting video.

Key Factors That Affect Panache Bra Fit

Your calculated size is an excellent starting point, but other factors influence the perfect fit. Being aware of them will help you choose the best style.

• Breast Shape: Are your breasts full on top, bottom, or teardrop-shaped? Some styles, like a balcony bra, suit bottom-full shapes, while plunge styles work well for less upper fullness.
• Breast Root Width: The ‘root’ is where your breast tissue starts on your chest. If you have wide roots, you’ll need styles with wider underwires to avoid painful digging at the sides.
• Breast Spacing: Are your breasts close-set or wide-set? This affects the gore (the center part of the bra). Close-set breasts need a low, narrow gore, while wide-set breasts can accommodate a taller, wider gore.
• Tissue Firmness: Softer breast tissue might require a cup with more coverage or stretch lace to prevent spilling, whereas firmer tissue is often easier to fit.
• Sister Sizing: As shown in the table above, if the band feels wrong, you can adjust. A 34F has the same cup volume as a 32FF and a 36E. Panache themselves encourage being flexible with your size.
• Bra Style: Different bra styles (e.g., Balcony, Plunge, Full Cup, Sports Bra) are constructed differently. A molded T-shirt bra will fit differently from a non-padded lace bra, and you might need a different size in a Panache Sports Bra compared to a daily wear bra.

Frequently Asked Questions (FAQ)

1. Does Panache use UK or US sizing?

Panache exclusively uses UK sizing for all its lingerie and swimwear, which includes cup sizes like FF, G, GG, H, etc. Our panache bra size calculator gives you the correct UK size.

2. How do I convert my US size to Panache?

After D, the cup sizes diverge. A US G is a UK F. A US H is a UK FF. It’s always best to measure yourself and use a UK-specific calculator rather than converting, as band sizing can also differ.

3. What if I’m between band sizes?

Panache bands can be generous. If your underbust is 33″, the calculator will suggest a 34 band. If you prefer a very snug fit, you could try a 32 band and go up one cup size (sister sizing).

4. My calculated size seems wrong. What should I do?

First, re-measure to ensure accuracy. Second, remember this is a starting point. Breast shape and bra style play huge roles. Use the calculated size to try on a few bras and see how they fit. Check that the band is firm and the cups fully contain your tissue without gaping or spilling.

5. Can I use this calculator for Panache swimwear?

Yes, most Panache swimwear uses the same UK bra sizing as their lingerie, so this calculator is a great starting point for their bikini tops and tankinis.

6. Why doesn’t this calculator add 4 inches to my band measurement?

The “+4” method is an outdated technique from when bras were made with less elastic materials. Modern brands like Panache design bras where the band provides most of the support, so the band size should be very close to your actual underbust measurement.

7. What is a “sister size” and how do I find mine?

A sister size has the same cup volume on a different band. To find it, if you go down a band size, go up a cup size (e.g., 34F -> 32FF). If you go up a band size, go down a cup size (e.g., 34F -> 36E). The calculator automatically generates these for you.

8. Where are Panache bras made?

While Panache is a UK company established in 1982, their manufacturing is performed in factories across China, Vietnam, and Thailand, with a strong focus on ethical trading and quality materials.
