    THE LOOK

    A Refined Statement in Royal Blue

    Rich blue sequins bring shine to a fitted mermaid silhouette, while the V-neckline and long sleeves create a balanced, elegant look. Feather embellishment adds distinctive texture for prom and formal evening occasions.

    DETAIL VIEW

    Texture Meets Tailored Shape

    The V-neckline frames the upper body, and long sleeves provide added coverage. Sequin embellishment catches the light, while feather detailing gives the gown a more distinctive finish.

    Complete the look with understated earrings, a silver or navy clutch, and formal heels.

    3. Can I order this dress in custom measurements?

    Yes. The product listing offers a custom-made option for an additional $15. Take your measurements carefully and follow the store’s instructions when submitting them.

    4. How long will it take to receive my order?

    The listed tailoring time is 12–15 days, with an estimated delivery time of 2–6 days. These are separate time periods, so plan ahead for your event.

    5. Is an expedited production option available?

    7. How should I choose my size?

    8. What accessories pair well with royal blue?

    Silver jewelry and a silver or navy clutch complement the blue sequins. Keep accessories relatively simple so the feather embellishment and sparkling fabric remain the focus.
