US Bra Size Chart FAQ
To find your exact size using the US Bra Size Chart:
- Measure Your Band Size: Wrap a measuring tape snugly around your ribcage, right under your bust. Round this measurement to the nearest inch. This is your band size.
- Measure Your Bust Size: Measure around the fullest part of your bust, keeping the tape level. Round this measurement to the nearest inch.
- Refer to the Chart: Find your band size in the top row and your bust size in the left column. Where these measurements intersect on the chart is your bra size.
Example: If your band measurement is 34 inches and your bust measurement is 37 inches, look for these numbers in the chart to find your size, which should be 34C.
A sister size is a bra size that has a different band and cup size but offers a similar fit. For example, if you're a 34C, you might also find that a 32D or 36B fits well, depending on the brand.
To find sister sizes:
- Size Down in Band, Size Up in Cup: If your original size is 34C, try a 32D.
- Size Up in Band, Size Down in Cup: If your original size is 34C, try a 36B.
Using this chart, look at the row or column that aligns with your current band and cup size to see other sizes with similar measurements.
Many popular brands in the United States use the US bra sizing system, including:
- Victoria’s Secret: Known for a wide range of styles and sizes.
- Aerie: Popular for body-positive campaigns and diverse size options.
- ThirdLove: Offers half sizes and a variety of fit options.
- Warner’s: Specializes in comfortable, everyday bras.
- Playtex: Known for offering extended sizes, especially for fuller busts.
Even though the US sizing system provides a standardized approach, sizes can vary between brands due to different design approaches, materials, and fit philosophies. Some brands prioritize comfort and flexibility, while others focus on fashion and structure, which can affect fit.
To ensure the best fit, try your size in several brands, or consult a brand-specific size guide if available. Using the US sizing system as a starting point will help, but remember that slight variations are normal.
Body Changes: Weight fluctuations, hormonal changes, pregnancy, or age can impact your bra size. Measure yourself regularly to ensure you’re selecting the correct size.
Brand-Specific Fit: Some brands may have unique fits. If you’re unsure, check customer reviews or try on multiple sizes when possible.
Fit Across Styles: Not all styles fit the same way. For example, a sports bra might feel snugger than a balconette in the same size. Check the brand’s fitting notes for each style.
Measure Correctly: Make sure you’re standing straight and not pulling the tape too tight or leaving it too loose when measuring.
