Light Coats for Women: What to Wear from 50 to 70 Degrees, by Occasion
Light Coats for Women: What to Wear from 50 to 70 Degrees, by Occasion
The coat a woman wears most is not her winter coat. It is the light coat she reaches for from September to November and again from March to May, on days between 50 and 70 degrees when a wool coat is too warm and a blazer is not enough. This guide is organized by occasion, because that is how our clients actually shop: the office and travel, wedding guest and mother of the bride arrivals, and the weekend. Each recommendation gives the fabric content, the price and the sizes in stock today. Every coat is made in small runs in Europe, ships from California, and can be returned within 30 days. The full range is in the light coats collection.

Reading the temperature, not the calendar
A light coat works in a band of roughly 20 degrees. From 60 to 70 degrees it is worn open over a dress or a shirt. From 50 to 60 it is closed over a knit or a blazer. Below 50 it needs help, and below about 40 it should give way to a wool winter coat. What decides comfort inside that band is the cloth. A cotton blend with elastane breathes and recovers from travel. A wool and viscose jacquard at 340 grams per square meter holds a trench silhouette and adds warmth at the lower end. A polyester engineered for drape, with a Bemberg lining, gives the smoothest layer over silk and crepe. Luna publishes the fiber content of every coat on its product page, and that is the line to read first.
The office and business travel: the Iris short tailored coat and the Kim long coat
The Black Cotton Short Tailored Coat, Iris is the light coat our clients pack most. It is 81 percent cotton, 14 percent polyamide and 5 percent elastane, which gives it structure at the shoulder and recovery from a suitcase, and it is cut short enough to sit at a desk in without removing it. It layers over a blazer without bulk. It is $770 and in stock in sizes 2, 4, 6, 8, 10. The Beige Cotton Short Tailored Coat, Iris is the same coat in beige with a subtle satin finish, in sizes 2, 4, 6, 8, 10 at $770, and the Brown Short Tailored Coat, Iris is the saturated brown version in sizes 4, 8, 10 at $770. Black is the daily choice for a city wardrobe, beige for a warm-neutral capsule, and brown for the woman who already owns both.
The Beige Classic Long Coat, Kim is the choice when you want coverage over a dress and a coat that reads as formal the moment you arrive. It is a soft-touch premium polyester engineered for a cashmere-like hand and fluid drape, with a full Bemberg lining, a self-fabric belt and hand-finished interior seams. It is the coat for a board day that ends at dinner. It is $680 and in stock in sizes 6, 8, 10, one piece per size.
Wedding guest and mother of the bride: the Emma jacquard coats and the Rea trench
A ceremony in October or April is exactly the weather a light coat exists for, and the coat is in every arrival photograph. The Silver Floral Jacquard Light Coat, Emma is a refined jacquard with metallic threads, 90 percent polyester and 10 percent metalized fiber, woven into silver florals. It is made to be worn over a midi dress at a daytime or early evening wedding and it reads as part of the outfit rather than a layer over it. It is $880 and in stock in sizes 2, 6, 8, 10. The Teal Floral Jacquard Light Coat, Emma is the same coat on a black base with teal florals, for evening ceremonies and for women who want color without print on the dress itself, in sizes 4, 6, 8, 10 at $880. Both belong with the wedding guest dresses and jumpsuits and the mother of the bride outfits.
The Beige Jacquard Trench Coat, Rea is the neutral option for mother of the bride and mother of the groom. It is a wool and viscose woven jacquard at 340 grams per square meter, cut as a true trench with storm flap, gun flap, raglan sleeves and a D-ring belt, so it is warmer than the cotton coats and still light enough for a 55 degree afternoon. Beige jacquard photographs well against every dress color in the Luna range. It is $770 and in stock in sizes 2, 4, 6, 8, 10.
The weekend and travel days: the Isidora long textured coat
The Brown Long Textured Coat, Isidora is the relaxed piece in the collection. It is a European cotton blend with stretch, 55 percent polyester, 35 percent cotton and 10 percent elastane, with a woven jacquard texture, cut long. The stretch makes it the easiest coat to wear in a car or on a plane, and the mocha tone works over denim as well as over a knit dress. It is $680 and in stock in sizes 4, 6, 8, one piece per size.

Fit over a blazer and over a dress
Luna light coats are cut true to size. The shoulder seam should sit at the edge of your natural shoulder, and the coat should close without strain over a jacket. If you will wear the coat mostly over dresses and knits, take your usual size. If you will wear it over suiting every day and you are between sizes, take the larger size. The Luna sizing guide gives the measurement method, and returns are accepted within 30 days. Women under five feet four should read the most flattering coats for petite women before choosing between the short Iris and the long Kim.
Care
All of these coats are dry clean only. Cotton blend coats can be steamed lightly between cleanings and hung on a shaped hanger. Jacquard with metallic threads should go to a cleaner who handles eveningwear and be stored on a padded hanger so the weave does not crease. Never press an iron directly onto a jacquard face.
Frequently asked questions
What temperature is a light coat for?
A light coat is built for days between roughly 50 and 70 degrees Fahrenheit, which in most of the United States means September through November and March through May. Below 50 degrees a light coat needs a knit underneath, and below about 40 degrees a wool winter coat at 460 grams per square meter or more is the better choice.
What is the difference between a light coat and a trench coat?
A trench coat is a specific construction with a storm flap, raglan sleeves and a belt, originally made to shed rain. A light coat is any unlined or lightly lined coat in a mid-weight cloth. Luna's Rea is a jacquard trench in a wool and viscose weave at 340 grams per square meter, so it is both. The Iris and Kim are light coats without trench details.
Can I wear a light coat as a wedding guest or mother of the bride?
Yes, and for daytime and early fall ceremonies it is the correct weight. The Emma jacquard light coats in silver or teal florals are made for wedding arrivals over a midi dress. The Kim in beige and the Rea jacquard trench are the neutral options for mother of the bride and mother of the groom when the ceremony is outdoors or the church is cold.
Which light coat is best for business travel?
The Iris short tailored coat, in black or beige, is the one clients pack most. It is a cotton blend with elastane, so it recovers from a suitcase, it is short enough to sit at a desk in, and it layers over a blazer without bulk. The Kim long coat in beige is the choice when you want full coverage over a dress and a coat that reads as formal on arrival.
How should a light coat fit over a blazer?
The shoulder seam should sit at the edge of your natural shoulder and the coat should close without strain over a jacket. Luna light coats are cut true to size. If you will wear the coat mostly over dresses and knits, take your usual size. If you will wear it over suiting daily, and you are between sizes, take the larger one. Returns are accepted within 30 days.
How do I care for a jacquard or cotton blend coat?
All Luna coats are dry clean only. Jacquard with metallic threads should be cleaned by a cleaner who handles eveningwear, and it should be stored on a padded hanger so the weave does not crease. Cotton blend coats can be steamed lightly between cleanings. Never iron directly on a jacquard face.
