Discovering the right bra fit is crucial for comfort, support, and confidence.

If you’ve ever faced discomfort or felt the need to adjust your bra throughout the day, this quick 4-point bra fitting and measurement guide can help you spot common fit issues and lead you to the perfect fitx

1. Check the Cup Fit

The cups should fit your breasts snugly without spillage or gaping.

  • Go up a cup size if:
    • Your breasts are spilling out at the front or under the arms. This is a sign the cups are too small.
  • Go down a cup size if:
    • There are wrinkles or gaps in the fabric. This means the cups are too large and aren’t providing proper support.

2. Evaluate the Strap Fit

Straps should be supportive without digging into your shoulders or slipping off.

  • Loosen the straps if:
    • They dig into your shoulders or cause the cups to press into your breasts. This indicates the straps are too tight and putting unnecessary pressure on your shoulders.
  • Tighten the straps if:
    • They slip off your shoulders. Loose straps reduce the bra’s support, and those with narrow shoulders should avoid balcony bras for better fit.

3. Check the Underband Fit

The underband should sit level and snug around your ribcage, providing the bulk of your bra’s support.

  • Go up a back size if:
    • You see breast tissue bulging from the sides or top of the underband. This suggests that the band is too tight.
  • Go down a back size if:
    • The underband rides up your back or the breasts slip out from underneath. A loose underband won’t provide proper support.

4. Assess the Underwire Fit

Underwires should rest comfortably against your chest without causing pain.

  • Go up a back size if:
    • The underwires dig into your breast tissue or lift away from your breastbone. This usually means the band is too tight.
  • Go down a back size if:
    • The wires slip down towards your waist. This indicates the band is too loose and isn’t keeping the bra in place.

Why the Right Fit Matters

An ill-fitting bra not only causes discomfort but can also affect your posture and body health. A well-fitting bra should make you feel supported and confident, with the cups, straps, underband, and underwire all working together to offer the perfect fit.
