Deep Waterfall Mermaid Gown

Black mermaid maxi dress in stretchy lined jersey with a draped waterfall neckline, open back, and gathered hip detail, designed to skim the body and flare at the hem for formal events and prom.

Size guide

A. Bust width is measured where the bust is at its largest. It is recommended to wear a smooth, unpadded bra when measuring. Make sure the measuring tape lies straight across your back.

B. Applies to bras: Measure the circumference just below the bust. Take the measurement as tight as possible.

C. Waist width is measured where the circumference is at its narrowest.

D. Sash width is measured where the sash is at its widest.

Garment lengths: The length of the garment is measured from the shoulder. Skirt length is measured from the top edge of the waistband. Trouser length is measured on the inside of the leg and is stated in the text for each model.

Party and wedding dresses can be perceived as long as we want to give you as a customer the opportunity to adapt the dress to your height or your heels.

Measurement list for all brands: Bubbleroom, Chiara Forthi, Happy Holly, Moments.

Bra size: The correct bra size is determined by two measurements. Measurement under the bust (B) and bust width (Ae). The difference between these measurements determines your cup size. Ex. Measurement B under the bust = 74 cm, which means size 75 in circumference. Bust width = 88 cm. The difference between these measurements is 14 cm, which means cup B. Bra size 75B.

Tip! Does the cup not fit? Keep in mind that the cup grows with the circumference. If you go up in circumference, you may need to reduce the size of the cup.

Bra sizes

Measurement under bust (B)	Bra size
63-67	65
68-72	70
73-77	75
78-82	80
83-87	85
88-92	90

Now measure body measurement A (bust width). Wear an unpadded bra when measuring this measurement. The difference in cm between the bust width and the measurement under the bust determines your cup size.

This black mermaid maxi dress is made for formal events, weddings, prom, and evening parties when you want a close, flattering fit with a little drama at the hem. The draped waterfall neckline softens the look, while the fitted shape skims the body before flaring out for that classic mermaid silhouette.

The stretchy jersey fabric makes it feel easier to wear than many occasion dresses, and the lining adds extra comfort and confidence. A gathered detail at the hip gives the dress a more sculpted look, and the open back brings a striking finish that stands out beautifully from every angle.

Fit: Figure-skimming mermaid silhouette with flared hem

Neckline: Draped waterfall neckline

Back: Open back

Material: Stretchy jersey, lined

Length: 149 cm from shoulder in size S

Extra detail: Recycled polyester certified by a third party

It’s the kind of long black formal dress that solves the “what do I wear?” question for bridesmaid duties, black-tie events, and prom nights alike. Dress it up with heels and statement earrings, or keep it clean and simple—the textured finish and elegant shape already do most of the work.

Can I wear this in different seasons?
Yes, it can work year-round with simple layering: add a tailored blazer or evening wrap in cooler months, and wear it on its own with minimal accessories in warmer weather. The lined stretch fabric helps it feel comfortable for longer events.

What is the fabric like?
The jersey has some give, which can make movement and sitting easier than in many structured occasion dresses. It also includes recycled polyester, offering a more premium, breathable, and sustainable fabric choice.
