A little perspective

Ball gown vs Brain coral colony: length comparison

The shoulder-to-hem height of a ball gown is approximately equal to the colony diameter of a brain coral colony.

Brain coral colony

A brain coral colony is a living mound-shaped formation of coral polyps that secrete a grooved, dome-like calcium carbonate skeleton.

Ball gown

Defined shoulder-to-hem height: 1.5 m; defined specimen; range 1.45 m–1.55 m.

A defined full-length ball gown displayed on a dress form, measuring 1.5 m from shoulder line to hem and weighing 4 kg. The mannequin is contextual and is not included in the garment mass.

Defined examples — our methodology

The marked defined shoulder-to-hem height is calibrated. Unmeasured illustration details are representative.

Brain coral colony

Defined colony diameter: 1.5 m; defined specimen; range 60 cm–2 m.

A defined massive brain-coral colony 1.5 m across with a 900 kg wet skeletal mass. Species, growth form and cavities vary; the living grooved dome, not attached reef rock, defines the diameter.

Why this measurement?

Why we use 1.5 m

We compare the shoulder-to-hem height of a ball gown. This is an illustrative comparison value, not a claim that every example is the same. The recorded range is 1.45 m to 1.55 m.

A defined full-length ball gown displayed on a dress form, measuring 1.5 m from shoulder line to hem and weighing 4 kg. The mannequin is contextual and is not included in the garment mass.
