How to know you are wearing the right bra size ...
You can tell you are wearing the right bra size when it feels comfortable and meets the following fit criteria:
Band Fit (The Foundation of Support)
The band provides the majority of the bra's support, so its fit is crucial.
It should be snug, but not painful. You should be able to fit two fingers under the back band, but no more.
It should sit straight and level across your back, parallel to the floor. It should not ride up.
When trying on a new bra, use the loosest hook so that as the elastic naturally stretches over time, you can move to the tighter hooks to maintain a proper fit.
Cup Fit (Containment and Shape)
The cups should completely enclose your breast tissue without any spillage or gaping.
No Spillage: Your breast tissue should not spill over the top, sides, or under the arms (avoiding the "double-boob" effect). This indicates the cup size is too small.
No Gaping: The cup material should lie smooth against your breasts. If there are wrinkles or gaps, the cup size is likely too large.
Underwire Lies Flat: If the bra has an underwire, it should sit flat against your rib cage, directly under the breast crease, and not press on any breast tissue. The center gore (the fabric piece between the cups) should also lie flat against your sternum.
Strap Fit (Balance and Security)
The straps are meant to provide balance, not bear the full weight of your bust.
They should be snug but not digging in to your shoulders or leaving deep red marks.
You should be able to slide one or two fingers under the strap comfortably.
They should not slip off your shoulders; if they do, first try adjusting the strap length, then check your band size.
Movement and Comfort
Ultimately, a properly fitting bra should feel comfortable and allow you to move freely.
Lift your arms, bend over, and move around to ensure the bra stays in place and nothing shifts or pokes.
When wearing a fitted T-shirt over it, the bra should create a smooth, flattering silhouette with no visible lines or bulges.
Your bustline should ideally sit at the midpoint between your shoulder and elbow when looking in a side mirror.
If you experience persistent discomfort, pain, chafing, or have to constantly adjust your bra, it is likely the wrong size or style, and a professional fitting might be helpful.
