Dress Code Requirements: Malaysia's National Mosque enforces strict modest dress standards year-round. Women require full ankle-length coverage (pants or skirts), long sleeves covering wrists, and head covering (hijab). Men need long pants and shirts covering shoulders - absolutely no shorts, tank tops, or sleeveless clothing. Tight-fitting attire not permitted regardless of coverage.

Free Robes & Entry: Reception desk (Jalan Perdana entrance) provides brown robes if your clothing doesn't meet requirements - limited sizes available, so proper dress recommended. Completely free entry and guided tours in English at 10:30am, 2:30pm weekdays. Remove shoes before entering carpeted prayer areas - storage cubbies provided.

Optimal Visiting Strategy: Weekday mornings (9:30-11:30am) offer ideal lighting through the geometric latticework of the main prayer hall's 73-meter star-shaped dome. Avoid Friday prayer times (12:15-2:00pm) when mosque reserved for worship. The 18-pointed star dome and minaret represent Malaysia's 13 states plus five pillars of Islam.

Architectural Highlights: Allow 60-75 minutes to properly appreciate the space. The reflecting pool, marble corridors, and geometric ceiling patterns exemplify modern Islamic architecture. Photography permitted in designated areas only - staff will clearly indicate boundaries.
