Black Halter Keyhole Neck Satin Rhinestone A-Line Prom Dress

A soft halter keyhole neckline sets the tone, framing the face before a fitted, rhinestone-dusted bodice cinches gently at the waist and releases into a graceful A-line skirt that moves with every step. Turn around and the dress makes its second statement — a dramatic open back finished with a delicate button-and-loop closure at the nape. One of our most romantic long black prom dresses, now offered in 5 colors and sizes US2-26W. Browse more black prom dresses in our prom dresses collection.


Product Silhouette

A classic A-line silhouette with a clean, defined waist that gently flares below into a soft, floor-sweeping skirt — flattering, graceful, and easy to move in. See more flattering shapes in our A-line prom dresses collection.

Material

Smooth, fluid satin finished with an all-over grid of delicate rhinestones that catch the light with every movement. The dress is fully lined with a double-layer construction and clean, hidden interior seams.

Size and Fit

Available in sizes US2-US16 and 16W-26W. The bodice sits close through the bust and waist for a polished, supported fit, while the A-line skirt skims gently over the hips with room to walk and dance comfortably. Please reference our detailed size chart for exact bust, waist and hip measurements before ordering.

Styling Tip

Keep jewelry minimal to let the open back and rhinestone bodice shine — small stud earrings and a delicate bracelet are all you need. Finish with strappy heels and a soft updo or half-up style that shows off the keyhole neckline and open back.

Frequently Asked Questions

Is this a good black dress for prom?

Yes. The halter keyhole neckline, rhinestone-dusted bodice, and dramatic open back make it one of our most romantic long black prom dresses, and it also works beautifully for evening galas and formal events.

Can I machine wash this dress?

No. This dress should not be machine washed, as the rhinestones can loosen and fall off with agitation. We recommend spot cleaning gently with a damp cloth, or taking it to a professional dry cleaner for a full clean.

Does this dress run true to US formal dress sizes, and is it available in plus sizes?

This dress follows US women's formal sizing from US 2-US 16, and it is also available in plus sizes 16W-26W, so the same design is offered across the full size range. We strongly recommend measuring your bust, waist and hips in inches and comparing them with our size chart, rather than relying only on your everyday casual-clothing size.

Does this dress have a lining?

Yes. The dress is fully lined with a double-layer construction, so all seams are finished on the inside and nothing shows through from the outside.

How does the dress close, and will I need a strapless bra?

The dress closes with a small button-and-loop closure at the back of the neck. Because of the halter neckline and open back, a backless/strapless bra or adhesive cups pair best with this style.

How many colors is this dress available in?

This dress is currently available in 5 colors — Black, Champagne, Burgundy, Navy Blue, and Emerald Green — so you can pick the tone that best fits your prom or formal event.
