The Inverse Relationship Between Bra Cup Size and Bra Band Size

Did you know that your bra’s fit and comfort level are directly tied to the relationship between cup size and bra band size? The science behind the best-fitting bras for lift and side support can be tricky. That’s why determining your measurements and buying high-quality plus-size bras is crucial. 

Your bra’s fit matters, but whether your body type fits the status quo does not. You should feel cozy and supported regardless of your dimensions or style. Fit Au Max Lingerie helps build a beautiful foundation for your intimate wear, including full-figure bras with underwire and matching lace panties. 

Most women wear a bra every single day, so they want theirs to fit correctly and accentuate their curves no matter the occasion. This article will explain the inverse relationship between a full-coverage bra band size and cup size to help you shop smarter and look better. Let’s begin.

Facts About Bra Sizing 

There’s much more to bra shopping than choosing a cup size that fits your breasts. You must select something fashionable, comfortable, and practical that suits your budget. Many luxury brands offer high-end lingerie but fail to provide bra sizing guides or helpful information. Fit Au Max wants to empower full-figured women with sexy bras and panties sets that fit perfectly. 

Bra sizing requires attention to multiple details, so pause buying one-size-fits-all pieces from the department store. It’s better to understand how band and cup sizes relate when developing a tailored lingerie wardrobe. For example, not everyone is aware of the inverse relationship between band size and cup size.

Whenever your band size increases you will always go down in cup size, and vice versa. For instance if you used to wear a 36C and you want to try the band size 34, you will look for a 34D instead of a 34C.

Likewise, when moving from the band size 40 to 42, if you are  a size 40H to move to a 42 band size, your best option is a 42G, not a 42H.
Meanwhile, watch for bra straps that dig into your shoulders or cause your breast tissue to spill over the cup. You may want to invest in a larger cup size but remember to buy a smaller band size in relation to the change. And if your bra band rides up between your shoulder blades, it’s probably too big or time to replace it for something newer and better fitting. 

Straps slipping off your shoulders, even when you’re not slouching? It could be that your cups are too big for your breasts. Go down a cup size but move up in band size to find a comfortable bra for your body type. You might also have the wrong cup size if the center gore floats away from your sternum. 

Here are some other fun facts to consider: 

    • Your bra’s band accounts for 80% of your side support and lift. If the band size is wrong, you won’t get as much side support, and your breasts could sag. 
    • Some side support bras can lose their elasticity over time. The more you wash and dry underwire bras with side support, the less supportive they become. 
  • Pinching, poking, and sagging are signs that it’s time to buy a new bra. It should be impossible to feel the best-fit bras and panties for plus-size women. 
  • Lace underwire bras are beautiful and can provide tremendous support. However, the wire can’t work correctly if the band can’t hold it in place. Properly fitting lace bras with lift will feature an underwire that keeps the material pressed firmly against your body. Meanwhile, it won’t dig into your sides or leave unsightly marks on your skin. 

    DID YOU KNOW: Underwire bras that don’t fit right can cause bruising. .

    How a Perfectly Fitting Bra Should Feel 

    A perfectly fitting bra should feel fantastic – like a second skin. It should not bunch, pinch, poke, or droop. Also, you shouldn’t see the bra through your clothes or experience a wardrobe malfunction because of the straps, bands, or cups. The purpose of a plus-size bra is to hold your breast tissue despite its weight. Don’t settle for less. 

    You should feel your bra holding onto your body when you move around. You’ll know it’s the right size band and cup combo if you can walk, bend, and twist without having to readjust the garment. Meanwhile, your lingerie shouldn’t feel so tight that it makes you uncomfortable. Here are some tips to help you find the best full-figure support bra:   

    Bra Cup Size Measuring Tips 

    Many people believe a DD bra cup is massive, but it’s actually on the lower end of the spectrum. The average bra size starts there, but some women can fit into a J-cup. Follow these steps to find what suits you best: 

    Step One: Ensure all your breast tissue is contained within the bra cup. You might need to go up a size if there’s too much spillage. 

    Step Two: Do the “Scoop and Swoop.” This is when you scoop the breast tissue forward while pulling back on the underwire bra. 

    Step Three: Let go of your breast tissue and let it fill the bra cup. You can also lean forward to better sense your bra’s fit. 

    Always move up one size for every ¾-inch breast tissue spilling over the top of the cup. For example, suppose you typically buy F-cup bras but experience the “double boob” effect because the cup is too small. Try a G-cup instead or learn about the parts of a bra to determine your unique dimensions. 

    Remember that your bra cup size can change throughout the month and for other reasons. Each time you move up in cup size, your band size must also adjust. The general rule is that your band size gets smaller when your cup size gets bigger. 

    Bra Band Size Measuring Tips 

    Nearly 80% of women wear the wrong bra size because they don’t get the band measurements right. The primary bra band sizing guideline looks like this: 

    • You should be able to run two fingers around the parameter of your bra without getting stuck. The tight places are areas that need addressing. The loose areas will cause sagging breasts. 
    • The band should set level against your skin from front to back. If it hikes up in the back, it might be too tight. If it droops, it’s probably too loose. 

    Raise your hands above your head and pay attention to how your bra behaves. Does it stay in place or ride up your chest? Choose the best-fit bra to prevent your breast tissue from slipping up or down. However, don’t forget how your lingerie feels on your shoulders. A bra with balanced cups and band sizes should help take the pressure from other parts of your body.  

    Conclusion 

    Many women have never considered the inverse relationship between bra cups and band sizes. The larger your cup, the smaller your band. Find the best full-coverage underwire lace bras for good support and lift.
