Have you ever noticed a small space between your bra cups and your breasts, especially when you lean forward or wear a fitted top? That little gap can be frustrating, both in how it feels and how it looks. But don’t worry. It’s one of the most common bra fit issues women experience, and the good news is it’s completely fixable.
At Wacoal, we believe every woman deserves a bra that fits her beautifully, offering both comfort and confidence. Let’s dive into what bra gapping really means, why it happens, and how you can find your perfect fit.
What Is Bra Gapping?
Bra gapping occurs when the cups of your bra don’t sit flush against your breasts, leaving a visible space or wrinkle between your skin and the fabric. Sometimes, the gap appears on one side more than the other, and that’s normal too.
Think of it this way: if the cups are designed to hold your breasts comfortably and evenly, any empty space means the fit isn’t right for your shape or size. And while it may seem like a minor concern, gapping can affect how your clothes fit, how supported you feel, and even your posture throughout the day.
So, if you’ve ever noticed a gap under your shirt or when you move, you’re not alone. And more importantly, you can fix it.

Why Does Bra Gapping Happen?
There are several reasons why bra cups might not fit as smoothly as they should. Here are the most common ones:
1. The Cup Size Is Too Big
The number one reason for bra gapping is wearing cups that are slightly too large. When the cups are too roomy, your breasts can’t fill them completely, leaving that frustrating space at the top or sides.
2. The Band Is Too Loose
Your band provides most of your bra’s support. If it’s too loose, it can ride up and pull the cups away from your body, causing gapping.
3. Breast Shape Mismatch
Every woman’s shape is unique. Some are fuller at the top, others at the bottom, and some have more projection. If your bra’s cup design doesn’t complement your breast shape, gapping can happen even if the size is correct.
4. Changes in Weight or Hormones
Weight fluctuations, pregnancy, or hormonal shifts can all affect breast size and density, leading to slight differences in how your bra fits.
5. Worn-Out Bras
Over time, the elastic and cup structure in bras stretch out, losing their shape. When that happens, cups may start to gape even if they once fit perfectly.
6. Strap Adjustment Issues
Straps that are too loose don’t provide enough lift, while straps that are too tight can distort cup placement. The right adjustment can make all the difference.
7. Posture and Movement
Sometimes, gapping appears only in certain positions, like when you sit or lean forward. That’s because your breast tissue shifts naturally with movement.

How to Tell If You Have Bra Gapping
Not sure if your bra is gapping? Try these quick fit tests:
- Mirror test: Stand tall and look at your reflection. Are your cups lying flat against your skin?
- Lean-forward test: When you bend slightly forward, your breasts should fill the cups without spilling or leaving space.
- T-shirt test: Slip on a fitted top. If you notice wrinkling or puckering around your bust, it’s a sign of gapping.
A little fabric flexibility (especially in lace or thin materials) is normal, but visible space or folding inside the cup indicates a poor fit.

How to Fix Bra Gapping
Here’s the empowering part. Once you know why it happens, fixing bra gapping becomes easy.
1. Get Professionally Fitted
A professional fitting takes the guesswork out of sizing. Many women discover they’ve been wearing the wrong size for years! At a Wacoal showroom, we can help you find the perfect size and style for your body. You can also try our online bra size calculator from the comfort of your home.
2. Adjust Your Cup or Band Size
If there’s space at the top of your cups, try going down a cup size. For instance, from 34C to 34B. If the band feels too tight, go up a band size but adjust the cup accordingly (for example, from 34C to 36B).
3. Pick the Right Style for Your Breast Shape
Different bra styles are designed for different shapes, and matching them makes a world of difference.
- Full-on-bottom breasts: Try push-up or contour bras for a lifted look.
- Shallow breasts: Balconette or demi-cup bras provide natural shaping.
- Uneven sizes: Padded or molded-cup bras help balance and smooth the silhouette.
4. Adjust Your Straps
Make sure your straps are snug enough to lift your bust gently without digging into your shoulders. Sometimes, a small strap tweak can eliminate gapping instantly.
5. Replace Old Bras Regularly
Bras have a lifespan of about 6–12 months with regular use. If your favourite style has lost its elasticity, it’s time to refresh your collection.
6. Use Inserts or Padding (for Small Gaps)
If you’re between cup sizes or need a little extra fullness for a special outfit, small silicone or fabric inserts can help fill minor gaps and give a smooth finish under clothes.
At Wacoal, our goal is not just to help you cover up gapping, but to help you find a fit that feels made for you.
Tips for a Perfect Fit
- Get refitted every 6–12 months. Your body changes, and so should your bras.
- Rotate between 3–4 bras to preserve elasticity.
- Store bras flat or hang them to maintain cup shape.
- And remember: your perfect bra is one that makes you forget you’re even wearing it!
