Your root (where your breast tissue attaches to your chest) and the breast volume around it determine this criteria.
Projected shapes have more tissue around the root. Generally, projected shapes may have larger cup sizes.
Breasts can be full on the bottom or full on top, or even spread evenly between the two. This is pretty easy to determine! If you have more tissue above the nipple you are full on top, with the reverse for full on bottom.
This tends to correspond to the projected or shallow shapes, but not always! This is also something that can change with age.
Self-supporting breasts do well in wireless bras and other less supportive styles.
People with pendulous breasts often choose more structured styles with lift and support.
This plays into something we almost never think about: The design of underwires. Different brands use different underwires or sometimes even design their own specialty ones. This can play a big part in how a bra fits you.
Narrow roots tend to do well with narrower underwires.
Wider roots with wider underwires.
Be aware that if you are petite and wear a larger cup size that underwire height can also comes into play.
