How often should you buy new underwear? The honest answer: when a pair stops earning its place in the drawer, which for most men who rotate eight to ten pairs works out to refreshing a few pairs every six to twelve months. There is no expiry date stitched into the waistband, and the calendar matters far less than the condition. I have kept comfortable, well-made pairs for years and thrown cheap ones away inside a couple of months; the fabric decides, not the date.
TL;DR
- Replace underwear when a pair stops earning its place, which for most men rotating eight to ten pairs means refreshing a few every six to twelve months.
- Fading alone can wait, but dead elastic, holes, thinning fabric or a fit that bunches and rides means the pair is finished.
- Recurring rashes or irritation are your cue to stop nursing old pairs along and replace them.
- Wash on a cold, delicate cycle in a mesh bag and air-dry, because hot water and dryer heat are what kill elastic fastest.
- Ten pairs in rotation wear each pair half as fast as five, so keep the drawer deep, audit it twice a year and replace retirees with breathable cotton or modal.
The Signs a Pair Needs to Go
You do not need a rule of thumb when the evidence is sitting in your drawer. Replace a pair when you see any of these:
Color fading is the first and most innocent sign. Regular washing simply pulls dye out of cotton over time, and a faded pair is not a hygiene problem, just a tired one. If they still fit and feel fine, fading alone can wait.
Dead elastic cannot. When the waistband rolls, sags, or has stopped snapping back, the pair is finished; elasticity does not come back, and underwear that will not stay put fails at its one job. The same goes for fit that has changed: stretched-out fabric that bunches or rides is a daily annoyance you do not need.
Holes and thinning fabric mean the pair is past the point of sentiment. And if you are getting recurring rashes or irritation, stop nursing old pairs along entirely: worn fabric holds on to bacterial buildup more stubbornly than fresh weave, and your skin is telling you something. Used-up underwear is the cheapest health problem you will ever solve.
How to Make Underwear Last Longer
Refreshing the basics extends upward, see our best dress shirts for men.
The lifespan of a pair is mostly decided in the laundry. Hand-washing is the gentlest option for high-quality pairs, and nobody does it; the realistic version is a delicate machine cycle in a mesh bag, cold water, mild detergent. Hot water and aggressive cycles are what kill elastic and fade fabrics fastest.
Drying matters even more. Heat is the enemy of elastic, so skip the dryer when you can and let pairs air-dry; they need only a few hours. Do that, and good cotton and modal fabrics will look and fit like new for years instead of months.
Rotation is the quiet trick. A drawer with ten pairs in regular use wears each pair half as fast as a drawer with five, so buying a few extra pairs is not indulgence, it is maintenance. When I find a style I like, I buy three of the same pair at once; the drawer stays consistent and no single pair gets worn to death.
Buy Replacements Like You Mean It

When a pair does retire, replace it with something you actually want to wear: breathable cotton or modal, a waistband that fits today’s body, and a cut you have road-tested. If your rotation includes gym sessions, a proper athletic option is worth having too; our guide to shopping for a jockstrap covers that side of the drawer.
So, looking at the whole picture: check the drawer twice a year, retire what has faded, sagged, or worn through, wash the survivors gently, and keep the rotation deep. Your underwear does not need a schedule. It needs an honest audit.
FAQ
How often should you buy new underwear?
When a pair wears out, not on a fixed date. For most men rotating eight to ten pairs, that means refreshing a few every six to twelve months. NYU microbiologist Philip Tierno told Refinery29 that underwear has no expiration date: replace it when it frays or the elastic stops working.
What are the signs of unhealthy underwear?
Dead elastic, holes and thinning fabric. A waistband that rolls, sags or no longer snaps back will not recover, and stretched fabric that bunches or rides is a daily annoyance. Recurring rashes or irritation are another sign to retire old pairs. Fading on its own is cosmetic, not a hygiene problem.
How long should a man keep his underwear?
As long as it still fits and holds its shape. Well-made cotton and modal pairs can look and fit like new for years if you wash them on a cold, delicate cycle in a mesh bag and let them air-dry, while cheap pairs can be finished within a couple of months.
How many pairs of underwear should a man own?
Eight to ten in regular rotation. A drawer with ten pairs in use wears each pair half as fast as a drawer with five, so the extra pairs are maintenance, not indulgence. When you find a style you like, buying three of the same pair at once keeps the drawer consistent.
