The tool does not calculate lift height or cosmetic changes.

Site calculation methods →
Your observationConstruction or fit comparison
Padding design: Fixed paddingInspect the edges after settling tissue; padding occupies space inside the cup.
Padding design: Removable insertsCompare the fit with and without inserts to isolate their effect.
Padding design: Lift from constructionCompare lower-cup structure and shape rather than assuming padding is required.
Cup-edge result: Persistent overflowCompare additional usable cup capacity or a different inner edge.
Cup-edge result: Empty upper edgeCompare shape and padding placement instead of tightening straps to force contact.
Cup-edge result: Contained comfortablyCheck the neckline after leaning and wearing the intended top.

Padding changes where the breast sits and can reduce usable space inside a cup. In G cup sizes, compare whether lift comes from the cup shape, a lower sling, padding or a combination.

If removable inserts create overflow in a cup that contains comfortably without them, the inserts have changed the available space and position. Use that comparison to understand the effect before changing several other fit variables.

Judge the upper and inner edges after settling tissue and moving. A desired neckline is a preference, while persistent painful pressure is a fit problem. The planner identifies which construction change to compare; it does not calculate lift height or promise a particular appearance.

Settle tissue into the cup and inspect the upper and inner edges. Persistent overflow or wire pressure is a fit issue even if the neckline looks as intended.

  • Fasten a new adjustable band on a comfortable setting with room to tighten as it wears.
  • Place breast tissue fully inside the cups before judging the edges.
  • Check the fit from the side as well as the front, then repeat after movement.

Supply padding design, cup-edge result. Choose what you can actually observe or measure rather than the result you hope to see. If a field is unknown, resolve that detail before treating the output as a shopping instruction.

Judge containment after movement, not only the initial neckline.

The tool does not calculate lift height or cosmetic changes. Save the complete band-and-cup label with your observation so a later try-on can be compared on the same terms.

Compare the garment with and without its removable inserts, if it is designed to be used both ways. Padding occupies cup space and changes where tissue sits. Overflow that appears only after adding padding gives you a more specific clue than the general statement that G is too small.

Inspect the inner edge as well as the top after moving. The preferred neckline is personal, but persistent pressure is not a necessary price for it. Compare less padding, a different cup shape or a different complete size based on the observed problem. The planner cannot calculate lift height from your label.
