A navy blue maxi dress with ruffle sleeves and a slit

This navy blue maxi dress by Numoco is an evening dress built from a few clear lines: a deep V-neck, short ruffled sleeves and a skirt that opens in a slit when you walk. The fabric is plain and matte, so the cut does the talking.

It is 150 cm long in size S and 152 cm in XL, which is floor length on the model, and it comes in sizes S to XL.

The piece: model 223010 by Numoco

Numoco is a label that sells its occasion dresses through a Polish fashion wholesaler, and the supplier files this one under evening dresses. It comes in one colour, a deep navy.

The supplier's own description is unusually personal. It talks about the moment in front of the mirror and says the dress "doesn't shout". We read that as: no print, no shine, no trims. What you get is shape. The bodice is fitted to a seam at the waist and the skirt flares from there to the floor.

Who it's for

For you if you have a formal invitation and want a long dress that is easy to wear. A flared skirt gives your legs room, and the slit means you can take normal steps and climb stairs without gathering the fabric in your hand.

The neckline is deep. If you prefer more cover, plan a bralette or a brooch at the V before the day itself.

Closer look: what the maker's data and the photos show

  • Deep V-neck (maker's data)
  • Ruffled sleeves (maker's data); in the photos short cap sleeves that stand out from the shoulder
  • Slit on the leg (maker's data); in the photos on the left leg, opening from the upper thigh
  • Fitted bodice with a seam at the waist and a flared skirt to the floor (photos)
  • Plain matte navy fabric (photos)
  • Small metal tag at the waist seam (photos)

The data says nothing about a zip or a lining, and the photos do not show the back. Ask us before you order if you need to know.

Fabric and feel: polyester with 5% spandex

The composition is 95% polyester and 5% spandex. The spandex gives the fabric some stretch, which helps a fitted bodice move with you through a long evening.

In the photos the fabric is matte and falls in wide, heavy folds where the skirt opens. The supplier gives no fabric name or weight, so that is as far as we can describe it.

Fit and silhouette: fitted top, flared to the floor

Choose your size by chest and waist. Size M has a chest of 90 cm and a waist of 76 cm; size L has 96 and 80 cm. The hip figures are much wider, from 108 cm in S to 120 cm in XL, because the skirt flares. Your hips will not decide the fit.

Length matters more. At 150 to 152 cm this dress reaches the floor on the model, who wears heels. If you are shorter, count on high heels or a visit to a tailor for the hem.

Source: the maker's size table. It does not say whether these are garment or body measurements; the wide hip figures suggest the garment, since the skirt flares.

Styling: gold, beige or silver

The supplier suggests high heels or heeled sandals, a clutch and delicate jewellery, and names gold, beige and silver as the colours that go with navy. The photos follow that advice with clear heels, a gold-tone clutch and bracelets.

We would keep the neck bare or wear one fine chain, because the V and the ruffles already frame the face. Hair up shows the sleeves. For a winter event a cropped jacket or a wrap that ends at the waist keeps the long line of the skirt.

Occasions

The supplier lists a wedding, a gala, an important family celebration, a prom and a special dinner. Navy is a safe colour for a wedding guest, and floor length fits a black-tie dress code.

As the supplier puts it: change the accessories and you change the character of the dress.

Care: follow the label

The maker's data has no care instructions, so go by the label sewn into the dress. Hang it up as soon as it arrives, so the folds from the parcel can drop out before your event.

The wow detail: sleeves like small wings

The ruffled sleeves are short and stand away from the shoulder. On a dress this plain they are the one playful element, and they widen the shoulder line a little, which makes the waist look smaller by contrast. When you sit, the slit opens and the skirt spreads around you, as the second photo shows.
