How to recognise it
The edge shows right angles: a horizontal line across the chest and two straight lines up to the shoulders. It can be narrow or wide, shallow or deeper.
Where it comes from
Square necklines were fashionable in Renaissance and Tudor dresses. They regularly come back, especially on summer dresses and corset tops.
Who and when it suits
It shows the collarbones and accents the neck and shoulders, so it suits short necklaces. It works well with broad shoulders and a round face.
Variations and look-alikes
It comes narrow and deep or wide and shallow, gathered or bound, on corsets, dresses and knits. A very wide rectangular version is called a portrait neckline. It differs from a sweetheart in its straight lines.
How to style it
- A short necklace or choker.
- Hair up shows off the neck.
- Pairs well with puff sleeves.
- Round face: the angles add contrast.
