Packing underwear

depends.. generally not. more than 6-7. I would do laundry or wash in the sink.

I don't own 16 pair

I usually pack two a day if going someplace warm or where I’ll be hiking. A little less if I don’t expect to shower a second time. I like fresh undies after a shower.
But if I were to go for 14 days, I’d expect to do laundry halfway through. So 14, doing laundry.

The real question is, how many old pairs do you bring to throw away during your trip?

I often bring old underwear and pajamas on some trips to throw away so I have more room in my luggage for souvenirs!

(Most of the pjs have pinprick holes or stains, so while they are not "indecent" in case I have to evacuate in the middle of the night, they are not in a suitable condition to donate. )

16, probably. Like another pea, one for each day and a couple more "just in case "

My mom used to do this. Then one hotel they stayed in the house keeper kept taking them out of the trash can and putting on the bed so they didn't get thrown out. That was a hoot.

Cool idea! I scuttle wire hangers on trips. Start out with clothing on them to whip out and hang immediately upon arrival. Then once worn, the closthes go back sans hangers. Never thought of scuttling underwear LOL.

For trips longer than a week, I tend to pack a week's worth of clothing, including underwear, planning on laundry somewhere along the line. I take more than 7 outfits, though, to allow for different activities, maybe a couple of extra pair of underwear.

8, because I would wash them.

For 14 days regular temperature, I would pack 16. One for each day, and two spares.

I would also do a bathroom sink washing and hang dry, because these days.....between menopausal warm flashes, hot flashes, hot summer months....I am changing underwear up to 3-4 times a day. Fresh pair in the morning and fresh pair at bedtime, and if needed >> a fresh pair after a hot flash.....plus after running errands in hot climate, because it results in gross and sweaty.

I hate when my underwear is damp. 
I've keep two pairs of panties in baggies, in my purse....in case I need to change them while at work.

I feel so disheveled, unkempt, and gross.....if I keep on "hot flash >> been gross and sweaty" panties.

I'm a high maintenance panty wearer. 

For 14 days, between 10 and 14. I’d expect to have to wash sometime in that time frame.
For a shorter trip (day a week) I’d go with 8. For a longer trip (back to Oz for a month or more) still around 8-10, as I know I’d be doing laundry each week.

Depends if I have laundry access. I don't wash in the sink.

I always take 2-4 extra pairs because I usually get out of sync with showering and changing.

20. Underwear is small and I’m not spending my time at a laundromat while on vacation. I can rewear second layer clothes (pants, t shirts if I didn’t sweat too much) I’m not rewearing underwear. One pair per day plus a few extra. My answer changes to more if I happen to be on my period during the trip.

Our trips last between 14-19 days so I overpack. I also use my FoodSaver to pack our bundles of underwear/socks to save space. They get hard as a rock so they can also be used as a weapon if someone attacks us in our room. And yes, we have been known to get rid of old underwear while on trips.

Outer clothing:
I learned that I can do just fine with 1 pair of nice slacks (in case we go somewhere that needs dressier clothes)and 3 changes of clothes that are all coordinated and can be mixed up to give a different look.

My trips have been in warmer weather so I am not packing heavy sweaters or coats.

I try to get everything in 1 large suitcase.
