How Many Pairs of Underwear Should You Bring on Vacation

Packing for a vacation can be a mix of excitement and stress. We have all experienced that moment when you’re hunched over your suitcase, staring at a mountain of undies, thinking, “Do I really need this many?”

It turns out, most people bring way more underwear than they need. It’s time to resolve that issue with insight from the pros, a sprinkle of real‑world wisdom, and some cheeky packing hacks.

The “Days + 3” Magic Formula

Amanda Parker, travel expert extraordinaire, has simplified underwear packing forever: pack three extra pairs beyond your travel days. For a five-day getaway, that means eight pairs.

The extras are your built‑in safety net for unexpected swims, hikes, or just that feeling of pure bliss when you change into a fresh pair after a long day.

Other Smart, Real-Life Packing Advice

While Amanda Parker’s “days plus three” rule is the go-to formula, plenty of other travelers have their own tried-and-true underwear strategies.

The Health Expert Rule

Dr. Nicole Olson, a women’s health specialist, recommends the daily plus two method. It provides coverage for emergencies such as leaks, spills, or those sweaty days when you want to feel fresh again.

Frequent Flyer Strategy

Flight attendants and business travelers often pack about 25 percent more underwear than the number of days they are away. One cabin crew member explained that layovers can be lengthy, flights may get delayed, and unexpected changes are part of the job.

Having a small cushion of extra pairs makes a big difference.
