Benefits of Large Cup Sizes

Breasts Can Serve as Accessories

Some outfits need statement necklaces or accessories to hide the lack of cleavage when you have smaller boobs. Hear me out on this –  large breasts can actually serve as an accessory themselves! They can help draw attention to all the right places, especially when you simply tape your breasts when you wear plunging dresses.

Have Effortless Cleavage

The ability to get amazing cleavage without even trying is maybe one of the most notable benefits of having huge breasts. You won’t have to make your breasts bigger or wear a cleavage-enhancing push-up bra for large breasts. Low-cut and V-neck tops can help to further emphasize your cleavage and work great for date nights!

Get More Body Warmth

Adipose tissue (AKA body fat) provides the fat that promotes breast development and maturation. To keep the body’s temperature stable, it also stores extra energy and calories that can generate heat. So, what does all this mean in simplified terms? Larger cups contain more body heat, which is advantageous on chilly days!

Drawbacks of Large Cup Sizes

More Prone to Neck and Back Pain

Having naturally large breasts means you’re more likely to suffer from back aches and neck pain. This is because your back and neck muscles need to help carry the weight and alleviate pain from the chest. Your muscles may compensate by leaning forward, affecting your posture.

Have Puffy Areolas and Large Nipples

The areola is the pigmented round area on the breasts, whereas the nipples show the actual projection of the areolas. Bigger breasts also come with larger and more sensitive nipples. Weather and garment fabric can sometimes cause the nipples to protrude more, so you usually have to wear thickly-lined bras.

Get Bra Strap Indentions

Keeping bra cups in place can cause stress and pressure on the straps. Because of this, the straps may dig into your shoulders, pressing the skin and leaving marks. It will be harder if you’re wearing a pullover or racerback type of bra for large boobs since you won’t be able to adjust the strap length and tightness.
