Your first bra, without the guesswork.
In one sentence: a first bra is the first bra someone chooses to wear; a training bra is only one style that can fill that job. It does not train the body.
Start with the question you actually have: what a training bra is, whether it is time to try one, how shopping works, what comfortable fit feels like, or how a parent can help without adding pressure.

The 5-Point First Bra Fit Check
Whatever the label says, the garment still has to pass five real-world tests.
- Band: stays level and comfortably in place.
- Straps: remain on the shoulders without digging.
- Front: feels comfortable without unwanted gaping or compression.
- Movement: stays reasonably stable when arms lift, bend and twist.
- Comfort: does not need constant adjusting.
