Learn how to measure for a bralette, understand sizing quirks, and choose the right style for your body with our expert guide.
Quick Answer
To find your bralette size, measure your underbust and full bust in inches, then use the band size (underbust) and cup size (difference) to determine your size. Bralettes often run small, so consider sizing up if between sizes or if you prefer a looser fit.
Bralettes are a comfortable, stylish alternative to traditional underwire bras, but getting the right fit can be tricky. Unlike bras with rigid sizing, bralettes often use S/M/L or numbered sizes that vary by brand. This guide will help you measure correctly, understand sizing differences, and choose a bralette that flatters and supports.
Whether you're shopping for everyday comfort or a special occasion, the key is to focus on band fit and cup coverage. We'll walk you through the steps and point out what to look for in different styles.
How to Measure for a Bralette
Start with a soft measuring tape. Wrap it snugly around your ribcage, just under your bust, and note the measurement in inches. This is your band size. Then, measure around the fullest part of your bust, keeping the tape parallel to the floor. The difference between the two numbers gives you a starting point for cup size.
For bralettes, many brands use a simple S/M/L system. As a general rule, if your underbust is 28-30 inches, you're likely a small; 32-34 inches, medium; 36-38 inches, large; and 40+ inches, XL. However, always check the brand's size chart, as some bralettes are designed with less stretch and may require sizing up.
- Measure in inches for consistency.
- Wear a non-padded bra when measuring for the most accurate bust measurement.
- If you fall between sizes, size up for comfort, especially if the bralette has a snug band.
Understanding Bralette Fit: Band, Cups, and Straps
The band is the foundation of a good bralette fit. It should sit horizontally across your back and feel snug but not tight. You should be able to slide two fingers under the band comfortably. If the band rides up, it's too loose; if it digs in, it's too tight.
Cups should fully cover your breasts without spillage or gaping. For bralettes with underwire (like some styles), the wire should lie flat against your sternum. Adjustable straps are a plus, as they allow you to customize lift and support. Remember, bralettes typically offer lighter support than underwire bras, so they're ideal for smaller busts or lounging.
- Check that the band doesn't ride up in the back.
- Ensure cups are smooth – no bulging or empty space.
- Adjust straps to lift without digging into your shoulders.
Bralette Styles and Their Fit Considerations
Different bralette styles fit differently. For example, a triangle bralette offers minimal coverage and is best for A-C cups. A longline bralette extends down the torso, providing more support and a smooth silhouette. A cupless bralette, like the Betony Cupless Underwire Bra, is designed for intimacy rather than everyday wear, so sizing focuses on the band and chain adjustments.
When choosing a bralette, consider the occasion. For all-day wear, look for soft, stretchy fabrics like the Yva Hi Cut Brief's fine lace. For a special occasion, a more structured bralette with underwire or embroidery, like the Yvonne Underwire Bra, might be appropriate.

- Triangle bralettes: best for A-C cups.
- Longline bralettes: offer more support and smoothing.
- Cupless bralettes: prioritize style over support.
Your Bralette Fit Decision Rules
- Measure both band and bust: Use a soft tape to measure underbust and full bust. Record both numbers in inches. Know your measurements before shopping.
- Check the size chart: Compare your measurements to the brand's specific chart. Bralette sizes can vary significantly between brands. Don't assume your usual size will fit.
- Consider the style: Think about the level of support and coverage you need. Triangle bralettes are lighter, while longline and underwire styles offer more structure. Match the bralette to your intended use.
- Size up when in doubt: If you're between sizes or prefer a relaxed fit, choose the larger size. A too-tight bralette is uncomfortable and unflattering. Comfort is key.
Bralette Styles to Consider
- Yvonne Underwire Bra: Yvonne showcases Dita's exclusive fine embroidery on sheer mesh in a dramatic navy 'After Dark' colour. The Yvonne Bra features lavish sheer embroidered cups with sheer insert 'sling' for lift and support. Rich velvet straps, and wire casing highlight the lurex details in the embroidery. If you want the comfort of a bralette but need more lift, this underwire style offers support without sacrificing elegance. The sheer 'sling' insert provides shaping, making it a good option for fuller busts.
- Betony Cupless Underwire Bra - Black: The Betony collection is made from gold chains and soft black laces with nothing to hide and all to be revealed. The Betony Cupless Underwire Bra is an erotic, revealing bra with detachable gold chain trims. For those seeking a daring, intimate piece, this cupless design focuses on aesthetic rather than support. Sizing is less about cup coverage and more about band fit and comfort.
Is a Bralette Right for You?
Best for
- Smaller busts (A-C cups) seeking light support and comfort.
- Lounging, sleep, or low-impact activities.
- Those who prioritize style and freedom of movement over maximum lift.
Not for
- Fuller busts (D+ cups) that need significant support and shaping.
- High-impact workouts where maximum support is essential.
- Formal occasions requiring a smooth, lifted silhouette under fitted clothing (unless choosing a structured underwire style).
Finding the perfect bralette fit is about more than just size – it's about understanding your measurements, the style, and your needs. Measure carefully, consult size charts, and don't be afraid to size up for comfort. With these tips, you'll be able to choose a bralette that feels as good as it looks.
