Can two people with the same bra size need different bras?

Absolutely. Breast shape differences like root width, projection, and fullness distribution mean two people wearing 34D may need completely different bra styles for the same fit quality.

How do I know if I have wide or narrow roots?

Look at where your breast tissue starts at your chest wall. If tissue extends into your armpit area, you likely have wide roots. If the tissue is concentrated in front with space before the armpit, you have narrow roots.

What breast shape is hardest to fit?

Projected breasts with narrow roots and full-on-bottom shape are often the most challenging to fit. They need deep cups, narrow wires, and good bottom support — a combination many mainstream bras do not offer.

Does breast shape change over time?

Yes. Breast shape changes with age, hormonal fluctuations, pregnancy, breastfeeding, weight changes, and fitness level. Your natural shape and tissue density also evolve, so periodic refitting is important even if your band and cup numbers stay the same.
