How Should a Wireless Bra Fit?

Most bras feel more like torture devices than supportive garments. Digging wires, pinching bands, and slipping straps will leave you with an achy chest at the end of the day.

Wireless bras mitigate some of these issues, but you still need to get sizing right. So, how should a wireless bra fit to get the support and comfort you need?

Bra sizing doesn’t have to be complicated. You can determine the right size for you with just a handful of measurements. We’ll walk you through everything you need to know, including how to avoid common fit problems and tips on maximizing the accuracy of online sizing charts.

There’s one other factor to consider after you learn how to choose band and cup size for wireless bras - finding the right brand for you.

Why Wireless Bras Are Better

We’ll dive into how to choose band and cup size for wireless bras later in this guide. But first, we need to address the question on your mind: Are wireless bras better for you than underwire bras?

We think so, and lots of women agree. They’re more comfortable without compromising on support. They give you the freedom to go through your day without pain. 

Less Restriction, More Freedom

How should a wireless bra fit you? Ideally, it should feel so comfortable and lightweight that you barely notice it's there. Wireless bras don’t need painful wires or inflexible straps to support you.

They feature innovative designs that hold everything in place for a natural lift without the pain. You’ll be able to go through your day focusing on what actually matters - crossing off tasks, running errands, or spending time with loved ones - instead of lamenting the pain of an underwire bra.

Comfort That Lasts All Day

We’ve all been there - we go through the ringer throughout the day, and finally return home only to practically rip off our uncomfortable bra. Sometimes we can’t even wait that long - we’re willing to take our chances in the parking lot just to feel comfortable.

As normal as this may seem, you don’t have to suffer all day long. Wireless bras don’t antagonistically dig into your back or cause unsightly boob sweat like underwire bras. Instead, you’ll hardly notice wireless bras at all - other than to feel supported and confident whenever you pass by a mirror.

Support, Reimagined

Underwire bras have a reputation as the “supportive” option. At first glance, it makes some sense - all that structure prevents sagging and excess motion. Conversely, some people believe that wireless bras lack in this category. The reality couldn’t be further from the truth. 

Think about it like this - what kind of “support” actively causes you pain? Underwire bras trade one problem (back pain from going braless) for another (back pain from hard metal pinching your skin).

So, how should a wireless bra fit? Simple - it provides the structure you need through innovative designs and quality fabrics. A wireless bra will work with your natural shape to smooth and lift without feeling rigid.

After all, no two bodies are the same. Wireless bras don’t try to stuff you into a cookie-cutter frame like underwire. That’s what we consider support.

How Should a Wireless Bra Fit? Sizing Tips For Your First Wireless Bra

How should a wireless bra fit? You deserve comfort, support, freedom from pain, and the confidence that comes with a smooth silhouette. Learning how to choose band and cup size for wireless bras will provide you with the all-day flexibility you’re looking for.

Everything begins with a handful of measurements. Get yourself a measuring tape and something to take notes in, and you’re ready to find your ideal fit!

Measure the Fullest Part of Your Bust While Standing Relaxed

We’ll need to take multiple measurements. After all, you’ll be moving around a lot throughout the day. The ideal comfortable fit in one position might be painful in another unless you consider every angle.

How should a wireless bra fit when you’re standing straight up? You’ll need to start by measuring the fullest area of your bust. Stand upright with your shoulders relaxed and arms down.

You’ll then wrap the measuring tape from the tips of your breasts, around your back until you make one complete loop. You don’t need to pull the tape too tight - instead, let it rest comfortably against your body.

Measure Snugly Under Your Bust For Band Size

Next, you’ll need to find your band size. This is typically the number you see in bra sizes, like 32AA, 36C, or 44E. Take the tape measure from the fullest part of your breast and place it directly underneath your bust.

You want to wrap it around to where you can fit a finger or two between the tape and your skin. This will give a snug fit that offers support and comfort.

Subtract Band From Bust - That’s Your Cup Size!

You’ll now take your first measurement minus the band size. The difference between the two will determine your cup size.

Generally, you’ll see this size displayed in letter form, like so:

• A Cup: 1-inch difference
• B Cup: 2-inch difference
• C Cup: 3-inch difference
• D Cup: 4-inch difference
• DD/E Cup: 5-inch difference

This continues through the letter I and beyond. Please note that cup size is always relative to your band size, as determined by this formula. 42DD bras will naturally be larger than 36DD bras due to the longer band.

This is why two bras with the same cup size but different band sizes (or vice versa) may feel entirely different on your body.

Full Coverage Matters More Than You Think

You’ve found your bra size, but how should a wireless bra fit on your body? Complete coverage is ideal for the best support and comfort. The cup should contain your entire breasts without spillage on the top or sides.

This will give you a secure feeling and a smooth silhouette. The goal is for your bra to adapt and be flexible around your chest, without forcing anything into place with the rigidity of underwire.

Try Moving Around in Your New Bra to Gauge Fit

How should a wireless bra fit on your body? It isn’t just about trying it on once. You need to test different ranges of motion to achieve comfortable all-day wear. Lift your arms overhead and from side to side, bend forward and backwards, and even have a little dance party at home.

These movements will give you a better idea of how the bra feels during your day. Notice how your chest feels during each motion. You’re aiming for support and comfort, rather than pain or excessive shifting.

Signs You’re in the Wrong Size

The only time you should notice your bra is when you get that burst of confidence staring back in the mirror. 

Digging straps, your band riding up, gaping cups, and spillage are all negative signs. Each of these will cause you discomfort and pain over the short- and long-term. 

You also shouldn’t need to adjust your bra manually - the best wireless bras adapt to your natural movement without demanding your attention.

Common Fit Issues (and How to Fix Them)

Once you have learned how to choose band and cup size for wireless bras, you’ll be most of the way towards finding a bra that fits perfectly.

However, it’s common to encounter a few fit issues in the process of finding your ideal size. Here’s what to do when you encounter them:

 

• Straps digging into you: You’ll experience this issue and might be quick to blame the straps in your bra. However, this is actually an issue with your band. It might be too loose, causing your straps to work harder to maintain the necessary support.

• Spillage from your cups: Full coverage is ideal for a wireless bra. Breast tissue spilling out from the cup is a sign that you need to move up a cup size.

• Gaping areas in your cups: This is the opposite issue of spillage. Too much room between your breasts and the edge of the cup will mean less support. Drop a cup size for a smooth fit.

• Band riding up: When your bra band rides up, your breasts will move around excessively throughout the day. This will cause aches and pains, especially after a busy day. You’ll want to try sizing down the band and increasing the cup size for a snug fit.

 

Don’t Be Shocked if Your Size Changes

Your bra size isn’t permanent. Natural shifts in hormones, weight, and tissue can occur for various reasons. We recommend re-measuring yourself once or twice a year. Some bras are flexible to evolve with your body, while others may require replacement.
