How Do I Know the Right Implant Size for Me?

Short answer: The “right” size isn’t about a cup letter—it’s about what fits your body, lifestyle, and goals. And no, you don’t have to figure it out alone.

You’ve thought about it a hundred times...

Standing in front of the mirror. Scrolling through before-and-afters. Wondering:

“How big is too big?”
“What if I go too small and regret it?”
“I don’t want them to look fake—but I also want to see a difference.”

Totally normal. Choosing your implant size is one of the most exciting and overwhelming parts of planning breast surgery.

So let’s take the pressure off—and walk you through it, clearly and compassionately.

How do I know what implant size is right for me?

Here’s the truth:
There is no one-size-fits-all.
Your body is unique. Your goals are personal. And your “perfect size” is based on so much more than a number.

At your consultation, a good provider will take into account:

• Your body frame and chest width
• Your breast tissue and skin elasticity
• Your activity level and lifestyle
• Your vision—whether that’s subtle and natural, or full and lifted

As Dr. G explains:
“It’s not about a number—it’s about what fits your body.”

So… should I just tell my surgeon I want a full C or D cup?

Not exactly.

Bra cup sizes are wildly inconsistent between brands (and bodies). What’s a “D” on one woman might be a “full C” on another.

Instead of aiming for a letter, we’ll talk about the look you’re going for:

✅ Natural but noticeable
✅ Fuller upper pole (top of the breast)
✅ More cleavage
✅ Better balance with your hips
✅ Subtle and soft
✅ Athletic but curvy

Bring photos of results you love—we’ll use those as a visual guide for what’s realistic for your body.

What if I’m between two sizes?

That happens all the time. If you’re torn between going slightly smaller or slightly bigger, here’s what many women find helpful:

• Go with the size that matches your lifestyle (active vs. glam)
• Ask how the size will look in clothes and without
• Trust your gut feeling—you’ll know what feels like “you”

Bonus tip: many women who choose the slightly larger of their two options are happier long-term (as swelling goes down and their body adjusts).

Can you help me decide during the consult?

Absolutely—and we wouldn’t let you go through it alone.

At your consultation, we’ll:

• Compare real before-and-after photos of women with similar builds
• Talk openly about your lifestyle, aesthetic goals, and insecurities
• Give honest, experienced recommendations based on years of successful outcomes

You don’t have to know your perfect size walking in.
That’s our job—to help you discover what fits you best.

What if I regret the size I chose?

That fear is so common—and valid. The key to avoiding regret is honest conversation before surgery. Your provider should:

• Tell you what to realistically expect
• Help you weigh pros and cons of different volumes
• Make sure your size fits your anatomy, safely
• Never pressure you to go bigger or smaller than what feels right

And if your vision ever changes down the line? You’re not locked in forever. Implant exchanges are possible when your body or goals evolve.

Final thought?

The “perfect size” isn’t on a chart—it’s what makes you feel amazing in your skin.

Whether that’s subtle enhancement or a bold transformation, the right implant size should:

✨ Fit your frame
✨ Fit your lifestyle
✨ Fit your confidence
