have a question?
we have answers
How many pairs of underwear should I have?
Ideally, you should own 15 to 20 pairs of underwear. That allows you to have enough time between washings and a sufficient number of clean pairs at your disposal.
How often should I wash my underwear?
You should wash your underwear after every single wear and follow the provided care instructions. We’re assuming that only you are wearing them and that it’s not some weird boxer brief time-share situation. 
Should my underwear be tight or loose?
For maximum comfort, you should aim for somewhere in the middle. Your underwear shouldn’t be so tight that it leaves marks on your skin, nor should it be loose enough to fall down your waist or bunch up.  
Should I wear underwear to sleep?
It’s totally up to you whether you want to sleep in the buff or curled up in your favorite boxer briefs. Sweet dreams.
