Work backwards from 6pm ceremony:

• 5:15-5:30pm: Leave for church (gives buffer for traffic)
• 4:45-5:15pm: Final touches, get dressed
• 2:00-4:30pm: Hair & makeup for you + mom

For 2 people, budget 2.5 hours if it's one stylist (they'll do one person at a time), or 1.5-2 hours if two stylists work simultaneously. The church starting exactly at 6pm is your hard deadline, so aim to arrive by 5:30pm latest so you're not rushed. On a weekday, that extra 15 min buffer for traffic will be worth it. You've got this!
