Bikini 70E or 70F? 3 Essential Tips for Women with a Large Cup and a Small Band Size
You see a beautiful bikini online, check out the available sizes, and once again end up disappointed. The sizes are small/medium/large, and the back panel isn’t adjustable. You know you’ll need an L or XL for your cup, but it would be far too loose on your back.
You continue browsing; here’s a bikini you also find attractive—and it comes in cup sizes! However, the sizes start at a 75 measurement, and the cup sizes only go up to D. Still, you decide to give it a try, hoping it might fit well. When it arrives, you try it on with hope, but as soon as you wear it… it’s off again. The cups are too tight, the band is too wide, and proper support is nowhere to be found.
Many women with a large cup and a small band size (such as 70E, 70F, or 70G) face these challenges. Regular bikinis are often designed for “standard sizes” and don’t take into account a fuller bust combined with a small band size.
Fortunately, there are options that not only fit well but also look great. In this blog, you’ll discover 3 essential tips to finally find a bikini 70E or bikini 70F that fits perfectly.
Did You Know:
The founder of Via di Gioia has cup 70F and struggled with this issue for years! This was the main reason she started the brand!
1. Choose a Measurement that Truly Fits | Essentials for Your Bikini 70E, 70F & 70G
Since 80% of the support comes from your measurement—not the shoulder straps—don’t settle for a bikini in size M when your circumference is 70 cm, because it will never fit snugly. Also, avoid a bikini with a measurement size of 75 when size 70 isn’t available. The band will ride up on your back, causing the cup to tip forward. And nobody likes cups that open up a bit.
If you have a large cup and a small band size and are looking for a bikini 70E or bikini 70F, it’s extra important that the measurement fits well. A snug fit ensures you get the proper support, without the bikini feeling uncomfortable or shifting.

2. Choose High-Quality, Sturdy Fabrics | Essentials for Your Bikini 70E, 70F & 70G
With a larger cup, you want your breasts to be lifted. They should sit a little higher, and perhaps a bit closer to your body, so that the upper part of your bust looks full and voluminous. Firm cups can provide this support, but they may also make your breasts appear slightly larger than they are—and they remain wet for a long time. You know the feeling: leaving the sea and having to squeeze your breasts before heading back to the beach.
If you want the support of a firm cup without the look of making your breasts seem larger or staying wet on the beach for too long, opt for a bikini with an extra thick fabric. Preferably, choose a sturdy fabric that feels soft against your skin and has high stretch retention. This way, you get as much support (often even more, as the fabric molds better to your skin). That’s ideal for a bikini 70E, 70F, or 70G!
Thinner, cheaper bikini fabrics might offer some support because your breasts simply hang through them. However, they tend to stretch even faster over time, resulting in even less support. Moreover, these thinner fabrics often have poor stretch retention—when stretched repeatedly, they rebound less and begin to sag.

3. Choose a Cup that Supports the Sides of Your Bust | Essentials for Your Bikini 70E, 70F & 70G
Breasts often tend to fall slightly outward, especially when your cup size is larger. If you wear a bikini that doesn’t address this, your breasts might appear wider (and sometimes larger) than they actually are. If you already have a large cup—like cup 70E, 70F, or 70G—that might not be something you want (or need). Moreover, a small, subtle décolleté can look very attractive, but it isn’t something everyone naturally has without support.
Centering the breasts (pushing them slightly inward) not only creates a beautiful, soft décolleté but also makes your bust appear less wide. And that’s achieved without a push-up effect! Because even larger isn’t necessarily what you want, but a subtle décolleté is definitely a plus!
Luxury bikini or lingerie brands that offer swimwear often apply this technique. The most effective way to center the breasts is by placing a non-stretch mesh fabric on the sides of the cup. Since the fabric doesn’t stretch, there’s no room for the breast to spill outward; consequently, the breast is pushed more towards the center of the torso, creating a beautifully soft décolleté.

4. Pay Attention to Adjustable Shoulder Straps | Essentials for Your Bikini 70E, 70F & 70G
For a fit that perfectly conforms to your body, the shoulder straps need to be the right length for you. Their function is to ensure that the bikini top sits snugly against your body and doesn’t shift. They can also give your bust a slight lift. If the shoulder straps are too loose, the bikini top won’t sit well against your breasts, depriving you of optimal support and lift. If they are too tight, they dig into your shoulders and pull the back of the bikini top upward. As a result, the underwire of your bikini rests diagonally on your ribcage, causing your top to fall slightly forward. This underwire then irritates you and feels uncomfortable against your skin.
In a bikini 70F or bikini 70E, it is essential that the shoulder straps are adjustable so you can fully adapt the fit to your body and always get the right support.

Insight: This is the main reason why many women dislike underwire bras! When the measurement is too loose, the bra shifts forward slightly, causing the underwires to rest diagonally on the ribcage—which feels uncomfortable. So, what do women do? They buy a bra in an even looser measurement, thinking that the underwire will be less irritating. But that bra offers little support (remember, 80% of the support comes from the measurement), causing them to tighten the shoulder straps even more. As a result, the bikini top tips further, and the underwire sits even more diagonally on the ribcage (or even begins to shift a bit, which isn’t pleasant). This leads many women to think: “I’m completely done with underwire bras!”
Completely understandable, but the solution is to opt for a smaller band size.. It may seem counterintuitive, but give it a try! It feels much better and instantly provides your breasts with much more support!
That’s why it’s essential that the shoulder straps of a top are adjustable—especially if you have a large cup with a small band size and are looking for a bikini 70E, bikini 70F, or bikini 70G. Whether you have a longer or shorter torso, the bikini top will always fit beautifully and offer optimal lift and support.
