Costarellos Strapless Gowns: Draped Georgette, Silk Mikado and Sequins

Strapless is one of the strongest necklines in the current Costarellos edit, from draped lurex georgette gowns to a structured silk mikado dress. Six are available at Costarellos at Coveti, priced from $3,000 to $3,970. Here is how they differ, how they fit, and what to wear over them. For other houses, browse strapless dresses.

Quick answer

• Structured: the Avielle in dark green silk mikado ($3,270).
• Textured: the Gisella with petal lurex satin and tulle ($3,670).
• Shorter: the Harlee sequin dress ($3,970) and the Isabetta cotton velvet dress ($3,000).

Will a strapless gown stay up?

A well made strapless gown is held up by its own bodice, not by your shoulders, so the fit at the ribcage matters more than the fit at the bust. Order the size that fits your ribcage and waist snugly; a size that is loose under the arms will slip. A long line strapless bra helps on draped styles, and a tailor can add silicone grip tape inside the top edge. The structured Avielle needs the least help; the draped Lenina and Minari benefit from a fitting.

What to wear over a strapless gown

A matching long sleeve bolero is the neatest answer: the Sida bolero in Ciel pairs with the Lenina and the Minari. A wrap in the gown’s colour works for everything else. For the full guide, read how to wear a bolero with an evening gown.

Wearing it around the world

United Kingdom and Europe: winter black tie means a long wool coat over the gown and a closed pump; sheer black tights are fine under a long hem. North America: gala season runs from November to February, and a gown with a cover for the shoulders works for both the ceremony and the dinner. Gulf states: evening dress codes often ask for covered shoulders and arms, so pair a sleeveless gown with a long sleeve bolero and a wrap, and choose floor length. Australia: the party season falls in summer, so the lighter georgette gowns suit outdoor evenings better than velvet. Coveti ships Costarellos worldwide.

How Costarellos sizing works

Costarellos cuts in French sizes, FR 34 to FR 46 for most gowns. Subtract 28 for the UK size: FR 36 is a UK 8 and a US 4. Most styles carry the house note “true to size”, and the model on the brand site is 180cm wearing FR 36. Where a style fits differently, the note on the product page says so, and the table above repeats it. For measurements, read the Costarellos size guide.
