Square Neck Dresses: Why the Neckline Works, and 9 Designer Styles
The short answer: a square neck dress frames the collarbones with a straight, architectural line, so it suits almost every body shape and needs very little jewellery. For an evening, our first pick is the Imogen Midi Dress by Rebecca Vallance, a black long sleeve midi with a square neckline edged in diamante trim. For a day wedding, choose the Christopher Midi Dress, an ivory crepe midi with a square neckline, a bow trim and a circular skirt. See every style in designer midi dresses.

The square neckline has been a signature of European dressmaking since the Renaissance, and it has come back because it does something no other neckline does. It is open without being low, it widens the shoulder line slightly, and it gives a structured dress a clean frame. Rebecca Vallance uses it across the collection, on crepe, cotton, sequins, tweed and jacquard, which makes it a good place to see how the neckline changes with the fabric.

How to wear a square neck dress
Jewellery: A square neck leaves a clean space at the collarbone. A short pendant and a choker both sit well inside it, and going without a necklace works too. Long necklaces cut across the line.
Who it suits: almost everyone. It balances narrow shoulders by widening the line, and it gives a fuller bust a supported, structured frame. Wide straps make it easier to wear a regular bra.
Hair: Up shows off the neckline. Down works too, since the neckline is wide enough not to be covered.
Sizing: Rebecca Vallance says its dresses fit true to size, and AU sizing matches UK sizing. Our size guide has the chart.
