In September 2012 the first Hello Molly website started taking orders in Sydney, and by the label's own timeline the first item it ever sold was a pair of pants. Not a dress. I like that, because it means everything since has been a decision rather than an origin story.

 

The decision, according to a 2015 Sydney Morning Herald profile, came quickly: within months it was clear the business focus should be party clothes and memorable dresses. That is still the point of view. The brand describes its customer as free spirits, dream chasers and trend lovers with a full social schedule and an outfit for every occasion, and it says it releases more than 100 new styles every week. So Hello Molly dresses are built for the calendar, not for the quiet shelf of the closet. Birthdays, brunches, a Saturday that becomes two parties. I went deeper on a related idea in Bridal After Party Outfits: Mini Dresses, Clutches and Platforms.

 

Minis are where that logic is easiest to see, and they suit an October weekend with opaque tights and a boot. In my fashion dreams she is walking into a rooftop birthday in the Flirty Florals Mini in pink, a cropped jacket over her arm. The Now Or Never Girl in yellow floral is chiffon, lightweight and non-stretchy, so I would size by the bust and not count on give. The Style Files Strapless in brown and the Wild Rose Affair Strapless in pink both lean on a clean neckline, and I would wear either with a long coat for the walk there.

 

For something sharper, the Pearl Radiance one shoulder satin in red and the Flawless Formula halter satin in chartreuse do all the talking. Practical test: the product pages list the length from bust or shoulder to hem in size S, from 62 cm on the Wild Rose Affair to 80 cm on the Everyday Happiness Polka Dot in brown, so hold a tape to your own thigh before you decide.

The name came, as a founder told that same Sydney paper, from brainstorming the most friendly sounding girl's name they could think of. Keep that in mind with the midis, because they are the friendliest lengths in the edit: dressy enough for dinner, easy enough to sit in.

 

Satin does the heavy lifting here. The Dressed For Desire in brown and the My Fierce Love in brown are both satin, and the My Fierce Love is listed as lightweight and non-stretchy, so it will skim rather than hug. The shoulder-to-hem measurement is 90 cm on that one, which lands as a shorter midi, while the Dressed For Desire runs 132 cm from bust and sweeps toward the ankle. I would put the long one with a pointed flat and a wool coat in October. If you want to keep going, Bridesmaid Dresses: Long, Midi and One Shoulder Gowns for a Mixed Wedding Party is the one I would read next.

 

The Precisely Her strapless bandage midi in pink is the structured option, and the Floral Standout in black has a textured white floral neckline over a straight skirt, which I would wear with a slim belt and nothing else busy. The Stylish Boardroom in wine is the one for a work dinner that runs late. The Polka Dot Charm in navy has a flowy skirt and is the easiest to dance in.

 

Fitting test: sit down in it, then lift your arms. A strapless bandage shape should stay put without a tug, and a satin skirt should not ride up when you cross your legs.

 

What I would skip: the longest midis if you plan to walk a lot in flats, since a hem near the ankle collects every puddle in a wet October.

Hello Molly says its collections are designed in its Australian headquarters, and the maxi range reads like it: lots of neckline work and very little fuss in the skirt. Halters dominate, so the first check is the tie or button at the neck.

 

The Night Life halter in berry closes with buttons and runs 145 cm from neck to hem, the longest of the set, so it wants a heel or a platform. The Hibiscus Hideaway in olive has a metal u neckline and gathered details, and the Pretty Girl Approved in brown has a fitted waist that makes the skirt do the swishing. I would wear that one with a leather jacket and boots once it gets properly cold.

 

For texture, the Dream Petal Path in teal is mesh with lace trim and a train detail at the front, and the Personal Best in black has a lace top and a v neckline. In my fashion dreams, she is heading to a late fall engagement party in the black lace one, with a velvet clutch and nothing on her wrists. The Stiletto Strut in sage adds a lace bodice with stretch, and the Lost In The Moment halter in green has a cutout at the neckline. The long sleeve ribbed maxi in brown is the quiet one, with a twist at the neck, and it is the one I would pick for a cold, plain Tuesday dinner.

 

Buying test: halters pull on the neck, so move your head side to side and check that nothing digs.

 

What I would skip: a sheer mesh skirt on a windy rooftop, unless you like an audience.

Dear Emilia, the in-house occasionwear collection the brand launched in November 2017, was introduced with a promise to be there for every formal, birthday and graduation. The pieces below carry that same job, and wedding season has its own rules: keep white, ivory and anything close to it for the bride.

 

The sequin pair is the loudest. The Sparkling Affair halter and the Shimmer Glow, both in yellow, are floor-length, 133 to 137 cm from bust, so plan your shoes before the day, not in the car. Yellow sequins photograph warmly under evening lights, and I would keep the rest quiet: small earrings, a clean updo.

 

For something calmer, the Confidence Society off shoulder satin in black and the Formal Steps one shoulder in black are the ones that will not argue with a venue. The Modern Heritage off shoulder in black has stretch through the body, which is useful if the evening includes a sit-down meal. The Beach Theory strapless pleated in sage suits an outdoor ceremony, and the No Ordinary Girl embroidered halter in hot pink has embroidered florals and slight stretch. The Beyond The Ordinary in navy ties at the shoulders, so you can adjust it through the evening.

 

Check the zip and any lining by gently pulling at the seam before you commit, and walk up a flight of stairs to make sure the hem clears your toes.

 

What I would skip: black tie in an all-day summer wedding, and sequins at a morning ceremony.

The boning is the thing to look at first in this group. A corset bodice gets its shape from structure, not from the fabric stretching, so the Fashionably Sleek maxi in blue, with boning in the bodice, underwire and embroidery, behaves very differently from a slip.

 

The slips are the easy pieces. The Style Slip mini in blue has a flowy fit, and the Exclusive Parties halter mini in cobalt is shorter, at 64 cm from bust in size S. The Evening Energy maxi in green has a cowl neck and a crisscross back, and the Piazza Nights in chocolate is a long satin line that I would wear with a wool wrap. Satin shows every crease, so hang it in the bathroom while you shower.

 

On the corset side, The Corset strapless mini in pink also has boning, and the Sparkling Glow sequin corset mini in brown has a crisscross back that ties up. The Glitter Corset midi in light blue has a sweetheart neckline and spaghetti straps, and I would pair it with a cropped cardigan in October. The woman I picture turns up to a winter holiday party in the brown sequin one with black tights and a long coat. I also put together Cocktail Dress Edit: Sequin, Satin and Midi Styles for Party Season.

 

Fitting test: sit, breathe in, and raise both arms. If the bodice gaps or bites, go for the next size.

 

What I would skip: a corset under a tight jacket, which fights the structure.

I would begin with the occasion and then the length. If it is a dinner, a midi in satin. If it is a night out, a mini in satin with tights. If it is a wedding, a maxi that is not white, with a wrap for the evening air.

 

Then check the measurement. Every page lists the length in size S, so measure your own bodice and hem before you click.

 

The label began with a pair of pants and found its real subject a few months later. I still think the best thing about Hello Molly dresses is that they assume the evening is already booked.
