Turn heads with quiet sophistication — this is the dress that makes you feel effortlessly graceful again.

The Cassandra Bow-Back Maxi Dress flatters the feminine silhouette with gentle draping and a touch of playful charm. Designed to celebrate curves without clinging, it brings back the joy of dressing beautifully for yourself.

Elegant Silhouette
The flowing maxi design elongates your figure while skimming over the tummy and hips for a confident, feminine shape. You’ll feel poised and graceful from every angle — no shapewear required.

Statement Bow Detail
A soft, structured bow at the back adds just the right amount of drama. It draws the eye upward and creates a beautifully balanced profile that feels refined yet delightfully youthful.

Soft, Fluid Comfort
Crafted from a lightweight, breathable fabric that moves with you, not against you. The result is a dress that feels as comfortable as it looks elegant — perfect for long days or evenings when you want to feel your best.

Confidence from Every Angle
The open-back design reveals just enough while maintaining tasteful coverage, letting you feel sensual without stepping outside your comfort zone. Every movement feels intentional, every moment — beautiful.

Step into elegance today — stock is limited and this style won’t be restocked once sold out.

Every product page has a fit finder next to the size selector — three questions, one recommendation, a few seconds. These charts are for anyone who would rather read the numbers.

How to measure

  • Bust / chest. Around the fullest part, tape level, arms relaxed at your sides.
  • Waist. Around the narrowest part of your torso, usually just above the navel.
  • Hips. Around the fullest part, roughly 8 in below the waist.
  • Inseam. From the crotch seam to the floor, in the shoes you'll wear the trousers with.

Measure over the underwear you'd normally wear, not over clothing. Keep the tape snug but not tight.

How our pieces are cut

  • Dresses are cut true to size. If you are between sizes, take the smaller one — most of our dresses have ease through the waist.
  • Coats and jackets are cut with room for a knit underneath. Take your usual size; size up only if you layer heavily.
  • Knitwear is relaxed by design. Between sizes, take the smaller one unless you want an oversized look.
  • Trousers and jeans run true to size. Between sizes, take the larger one.
  • Shoes run true to size. If you have a wide foot, take half a size up.

Still not sure?

Write to info@halstead.com with your usual size, your height and the piece you're looking at. We'll tell you what we would pick — usually within a few hours. We would far rather get it right the first time than process a return.

We work in natural fibres — wool, cashmere, cotton, linen and full-grain leather.

Knitwear: cold hand wash or a wool cycle at 30 °C, no softener, dried flat and stored folded.
Coats: dry clean once or twice a season, stored on a broad wooden hanger.
Leather: wipe with a damp cloth, condition twice a year, never dry near heat.

Full guidance is on our Materials & Care page.

Before you order

How is this cut — will it fit if I am between sizes?

Use Find my size next to the size buttons: three questions about your height, build and how you like things to sit, and it gives you a size you can add to the bag from the same window.

As a rule, knitwear is relaxed and softens with wear, so the smaller size is usually right. Outerwear is cut with room for a knit underneath. Dresses and tailoring sit closer, and there we suggest the larger of the two. The measurements for this exact piece are in the Size & fit tab above.

What is it actually made of?

The fibre composition for this piece is listed in the description and on the label inside the garment. We work in natural fibres — wool, cashmere, cotton, linen and full-grain leather — and where a synthetic is blended in for stretch or structure, it is named rather than hidden behind a phrase like premium fabric.

How do I wash it without ruining it?

Knitwear: cold hand wash or a wool cycle at 30 °C, no fabric softener, dried flat and stored folded rather than on a hanger. Tailoring and structured coats go to a dry cleaner once or twice a season. Leather is wiped with a damp cloth and conditioned twice a year, never dried near a radiator.

The Materials & care tab above has the instructions for this piece specifically.

Is the colour true to the photographs?

The photographs are shot in daylight and retouched only for dust and creases, never for colour. That said, screens differ, and a deep navy or an olive can read warmer or cooler than it is on your particular monitor or phone.

If the exact shade matters, email info@halstead.com and we will describe it against something you already own — and if it still is not what you pictured, you have 90 days.

When will it arrive?

Two to four business days to pick, check and pack, then three to four business days in transit — five to eight business days in total, and shipping is free. You get a tracking link the moment it leaves the warehouse.

What if it is not right when it arrives?

You have 90 days from delivery, as long as the piece is unworn with the tags on. Email us with your order number and we send a printable return label the same business day.

Return postage is deducted from your refund — unless the piece arrived faulty or is not what you ordered, in which case we cover it in full.

Will my size come back if it sells out?

Not always. Collections are cut in limited runs for a season, so a sold-out colour or size may not return; some core pieces are made again the following year in a new palette. If you are waiting on a particular one, email us and we will tell you honestly whether it is coming back.

Do I save anything by ordering more than one piece?

Yes, and it applies on its own — there is no code to enter. Two pieces take 10% off, three take 15%, and four or more take 20%. The bag shows you how close you are as you add things.

Anything else, write to info@halstead.com — a person reads it, usually the same business day. We would far rather answer a question before you order than process a return afterwards.
