    FAQ

    Each product page includes a detailed size chart, and sizes may vary slightly between different items. Please check the size chart carefully and choose the size that fits you best.

    Items' option marked as Ready to Ship are typically processed and dispatched within 1-3 business days. Please note that the actual delivery date depends on the shipping method/carrier you selected at checkout.

    There are a few reasons this might happen:

    • Check your selection: Please verify your order confirmation. Our products often have two status options: "Made to Order" (requires production time) and "Ready to Ship" (in stock). Only the latter ships immediately.
      - If you selected "Made to Order" but we happen to have stock, we will prioritize shipping it to you.
    • Inventory Delays: Occasionally, there is a lag in our inventory system. You may have purchased an item that just sold out. In this case, we will email you to notify you.
      - If we do not receive a note or reply from you, we will automatically proceed to produce the item for you and ship it once completed to ensure you still get your order.

    Please remember that Total Delivery Time = Processing Time (Production) + Shipping Time.
    "Fast Shipping" refers to how fast the courier travels, not how fast we make the costume. Also, if your order contains multiple items, the processing time is determined by the item with the longest production time, as we generally ship the entire order in one package.

    The estimated shipping date for 'Made to Order' items is listed on the specific product page. For a more accurate update after placing your order, please contact our customer service team with your Order number.

    • If you have a specific date you need the item by (e.g., for a convention or event), please contact us with your order number. We will do our best to prioritize it, but please note that shipping times are estimates and not guarantees.
    • We can't offer refunds solely for shipping delays caused by external factors beyond our control, such as public holidays, severe weather, or customs inspections.
    • If your package is officially confirmed as lost by the carrier:Please contact our Customer Service immediately. We will assist in tracking the shipment and, if necessary, arrange a refund or free reshipment.Important: If you purchased "Worry-Free Delivery" (Shipping Insurance), please contact their support team directly instead of us for the fastest claims process.

    Please understand that estimated delivery times are for reference only. We appreciate your patience!
