PRODUCT DETAILS
What's in the Box
- Iridescent fish-scale tunic with sewn-in purple belt and gold shell buckle
- Flowing metallic purple cape with dramatic stand-away collar
- Gold foam crown with purple jewel centerpiece on elasticated band

This Mens King Neptune Costume brings the commanding presence of the Greek sea god Poseidon to any mythology event or costume party. The iridescent tunic shifts from teal to purple under the light, mimicking ocean depths, while the metallic purple cape flows with theatrical drama.
Standout piece is the structured stand-away collar — wired to hold its fan shape behind your head, giving you that ruler-of-the-seas silhouette. The gold shell buckle sits at the waist, foam gauntlets cover your forearms, and the jagged crown with its purple gem marks you as ocean royalty. High-sheen metallic fabrics catch stage lights and party LEDs beautifully.
Perfect For
Mythology-Themed Costume Parties: A natural pick for Greek gods gatherings, Roman mythology events, or any aquatic royalty theme. Pair with a trident prop for instant recognition.
Halloween & Convention Cosplay: Commanding presence for Halloween balls, comic conventions (especially if you're a Percy Jackson universe fan), or theatrical productions requiring oceanic deities.
Couples & Group Costumes: Coordinate with a sea goddess or mermaid costume for a nautical couples theme, or lead a group as the king of an underwater court.
How to Wear It
Pair with teal, emerald green, or deep blue trousers (pants not included) and comfortable shoes — sandals or boots work equally well. Add a trident prop and consider blue-green face paint or a flowing wig for full mythological immersion.
FAQ
Q: What size should I order?
A: Check the size chart for chest and length measurements. The tunic is sleeveless with a sewn-in belt, so fit is forgiving through the torso. If you're between sizes and want a more dramatic drape, size up.
Q: Do I need to supply my own pants?
A: Yes — pants are not included. The model wears teal trousers for styling; any solid-colour trousers in teal, green, or blue will complete the look.
Q: Is the collar rigid or does it flop down?
A: The stand-away collar is structured (likely wired) to hold its upright fan shape. It maintains the dramatic silhouette without needing adjustment.
Q: Can I wear this to a themed work event or is it too theatrical?
A: This is a deluxe-tier costume with high metallic sheen and dramatic proportions — perfect for parties, conventions, and theatrical settings. For a daytime work event, you might tone it down by skipping the cape and gauntlets.
Care: Spot clean metallic fabrics; avoid machine washing to preserve sheen and structure.
