Bra Fitting Guide

At Triumph, we believe that a perfectly fitting bra is the foundation of feeling comfortable, confident, and empowered every day. A well-fitted bra is more than just lingerie—it’s essential for your posture, breast health, and overall wellbeing.

Why Bra Fit matters

The right bra fit means all-day comfort, support, and confidence. It moves with you—no digging, slipping, or pinching—while enhancing posture and shaping your silhouette.

How To Measure

Accurate measurements ensure your Triumph bra fits perfectly for comfort and support. If you’re between sizes or trying new styles, sister sizing helps you find alternative band and cup combinations for the best fit.

The Swoop & Scoop Method

While measurements are essential, nothing replaces trying on your bra—using the ‘Swoop and Scoop’ method.

The Swoop & Scoop method helps ensure your bra fits properly by guiding all breast tissue into the cups. By leaning forward, fastening the band, and gently adjusting each breast, you achieve better comfort, support, and a more accurate fit. It's a key step in making sure your bra fits as it should.

What A ‘Perfect Fit’ Looks Like

5 key signs your bra fits right

1. It Feels Comfortable All Day.

2. It Stays in Place Without Constant Adjusting.

3. It Supports Your Daily Activities with Ease.

4. It Boosts Your Confidence and Enhances Your Look.

5. It Promotes Good Posture and Reduces Back Pain.

Bad fit warning signs

Skin chafing or irritation - Redness, blisters, or itching usually mean your bra is too tight.

Underwire discomfort – If the underwire digs into your breast tissue or arm, your cup size is off.

Band riding up – A band that rides up your back is too loose; if it rides up in front, the style isn’t right for you.

Breasts falling out underneath – A loose band or too-small cups can cause breasts to slip out.

Cup spillage – Bulging at the top or sides shows your cups are too small.

Cup gaping or wrinkles – Extra fabric or gaps mean your cups are too large.

Here's what to look for with different bra types

Comfort Wire

A Comfort Wire Bra should gently contour your shape without digging in. It should fit snugly around your ribcage, offer support without pressure, and move comfortably with your body for all-day wear.
Minimiser Bras

These bras reshape and reduce projection. A good fit ensures the breasts are comfortably contained without creating an unnatural flattened look.
T-Shirt Bras

Designed for a smooth, seamless look under clothing, these bras should fit snugly without visible lines or bulges. The cups must contour your shape for a flawless silhouette
Sports Bras

Support varies by activity—low, medium, or high impact—so the fit must provide the right level of compression and support without restricting movement. Straps and bands need to stay secure during exercise.
Wirefree Bras

Prioritizing comfort and light support, these styles should fit snugly but gently, embracing your natural shape without underwire pressure.
Strapless Bras

Fit is crucial for staying put without traditional straps. The band must be firm enough to support you while remaining comfortable and preventing slipping.
Push-Up Bras

Fit is key to achieving natural-looking lift and cleavage. The cups should fully contain the breast tissue without overflow, while the padding enhances your shape subtly.

9 Common Fitting challenges

Band Issues

Challenge: Band rides up, feels too tight, or digs in.
Solution: If it rides up, the band is too loose — go down a band, up a cup; if it’s too tight or digs, go up a band, down a cup. The band should sit snug and level and provide most of the support.

Cup Fit

Challenge: Cups gape or wrinkle, or there’s spillage/“quad-boob.”
Solution: Gaping/wrinkling = cup too big; spillage = cup too small. Try the next cup size, a different cup shape, or use the scoop & swoop to position tissue so the cup hugs smoothly.

Straps

Challenge: Straps dig in, slip, or fall off.
Solution: If straps dig, the band may be too loose — the band should carry the support; if straps slip, shorten them slightly, move to a closer-set or racerback style, or adjust placement so straps sit comfortably without bearing most of the load.

Underwire

Challenge: Underwire pokes, digs, or sits on breast tissue.
Solution: Usually the cup is too small or the band too big — try up a cup or down a band, or a different wire shape. A correct wire lies flat against the chest and fully encases the breast.

Gore (Center Front)

Challenge: Gore doesn’t lie flat or it digs in.
Solution: If it lifts away, cups may be too small or the band too loose; if it digs, cups may be too big or the style may not suit your shape. The gore should rest flat and feel comfortable.

Asymmetry

Challenge: One breast is larger than the other.
Solution: Fit to the larger side and use removable pads or inserts on the smaller side; stretch-lace or molded cups can visually balance the shape.

Orange in a Glass

Challenge: Cup looks empty or wrinkles like an orange in a glass.
Solution: Cup shape/size mismatch — try a smaller cup, a more projected style, or a different cup shape that fills the cup smoothly.

Tail of Spence

Challenge: Breast tissue extends toward the underarm.
Solution: Totally normal — scoop that tissue into the cup and try full-coverage or side-support styles that contain and support it.

Body Changes

Challenge: Pregnancy, breastfeeding, menopause, or weight changes affect fit.
Solution: Re-measure and update sizes as needed; choose adaptable styles (stretch lace, non-wired, multi-hook) that adjust with your body.

FAQs

My bra band rides up my back. What does that mean, and how do I fix it?

A band that rides up usually means the band size is too large and isn’t providing enough support. Try going down a band size and adjusting the hooks for a snugger fit. Remember, the band should feel firm but comfortable, as it provides most of your bra’s support.

I’m spilling out of the top or sides of my cups (quad-boob/side-boob). What should I do?

Spillage indicates that your cup size may be too small. Consider trying a larger cup size or a different style that offers fuller coverage. Using the ‘Swoop and Scoop’ method can also help reposition breast tissue into the cups for better fit.

My bra straps keep falling down or digging into my shoulders. How do I fix this?

Straps falling down usually means they’re too loose, while digging in means they’re too tight. Adjust the straps to distribute weight evenly without causing discomfort. Also, ensure the band is providing enough support—if not, straps may be overcompensating.

The center part of my bra (the gore) doesn’t lie flat against my chest. Why is this happening?

A lifting gore often means the cup or band size isn’t right. Try adjusting your size—if the gore doesn’t sit flush, the bra may be too small or the wrong shape for your breasts.

My underwire is digging into my armpit or breast tissue. What’s the problem, and how can I solve it?

Underwire discomfort often occurs when the wire doesn’t fully encase your breast tissue or the cup size is too small. Try a larger cup size or a different style that better fits your breast shape.

My cups gape at the top, even after scooping and swooping. What’s wrong?

Gaping cups usually mean the cup size is too large or the bra style doesn’t match your breast shape. Consider trying a smaller cup or a different style that offers a closer fit.

My breasts are different sizes. How do I find a bra that fits both comfortably?

Breast asymmetry is common. Choose the bra size that fits your larger breast comfortably and consider using removable padding or inserts on the smaller side for balance.

I’ve gained or lost weight, or gone through a life change (e.g., pregnancy, menopause). Do I need a new bra size?

Yes, weight fluctuations and life changes affect breast size and shape. It’s important to get re-measured regularly to ensure your Triumph bras continue to provide the perfect fit, comfort, and support.
