A stylish Mehndi night (Mehndi Ki Raat) invitation card with a dark navy blue background and a modern ethnic aesthetic. Incorporate intricate orange mehndi mandala patterns in the bottom corners, and a henna-adorned hand illustration on one side. Decorate the top with soft white hanging fairy lights to add a festive evening ambiance. Use a mix of elegant serif fonts and flowing script fonts in peach-orange and off-white colors. The main heading ‘Mehndi Ki Raat’ should be prominent in a stylish orange script. Maintain an elegant, warm, and festive vibe suitable for a traditional yet modern Indian bridal mehndi celebration.
