The Season Has Changed

If it’s warm outside but your wool pants and fuzzy sweaters are making your closet look like the dead of winter, you’re overdue for a cleaning session. Organizing clothes by season can cut down on clutter, and it’s especially important for people with small closets who can’t fit four seasons of clothes into their closet at once.

Because It’s a Mess

If your closet looks like it was taken from the set of a movie about a lazy, spoiled teenager, you probably already know you need to clean it out. If you’re overwhelmed by the mere thought of it, set aside a weekend or more for a complete closet organization.

You Start Working

If you’re starting your first job or going back to work after a break, you’ll need to evaluate your wardrobe to make sure it’s work-appropriate. Before you run out and buy an entirely new wardrobe, look through what you already have and make a list to see what can still work for your new job. Then with the list in hand, head to clothing stores to pick up the missing pieces.

You Start Working More Hours

People who work a lot of hours need efficient closets. As you declutter, move your work clothes to the easiest-to-reach spot in your closet. Consider establishing a work “uniform” (like dress pants, a button-down shirt, and ballet flats), at least for stressful Mondays. Finally, choose simple, time-saving outfits; many women find dresses easier to wear than separates.

You Stop Working

Maybe you’re retiring, or just moving from a formal office to working at home or in a more casual environment. If you’re left with a closet full of smart slacks and crisp button-downs that you will never wear again, it’s a good time to donate those items to someone who needs them.

You Begin Going To the Gym

When you take up a new activity requiring new clothes, support your good habit by making it easier to retrieve and wear your workout gear. Dedicate an entire “fitness drawer” to gym clothes and separate your sports bras and workout socks from their dressier counterparts.

You Stop Going To the Gym

Whether because of an injury or a priority shift, if you are no longer using the clothes in the “fitness drawer,” then free up that space for other items. While you’re at it, see what other unworn clothing is lurking in your closet.

You Add a New Member of the Household

Maybe you are having a baby and need space for maternity wear or baby clothes. Or maybe you are suddenly sharing space with a new partner or roommate. Whatever the reason, an increase in household members requires you to clear out some room by removing any closet clutter you can find.

You Begin a Hobby or Stop Doing a Hobby

Whether you’re giving up skiing or getting really into historical reenacting, a change in hobbies can leave you with a lot of unworn clothes or a lot of new clothes that don’t fit easily into your closet. Take this opportunity to sort through your closet and decide what stays and what goes.

You’re Feeling Blue

If you’re sad or stressed, the cause could be your cluttered home. A UCLA study found a link between “levels of diurnal cortisol, a measure of stress,” and “how families, especially mothers, talk about their home spaces.” Women who used words like “mess,” “not fun” and “very chaotic” when talking about their homes had higher stress levels.

You Suddenly Start Going To More Social Events

If you are suddenly going out more, especially to the sorts of places or events you rarely attended before, you probably need new clothes. This can demand a wardrobe shake-up even more dramatic than starting a new job.

You’ve Gotten Older (And Your Clothes Haven’t)

If you’re still wearing the same clothes you wore 10, 20, or 30 years ago, it’s long past the time for a good closet clear-out. This goes double if you’re not even wearing your old clothes, but still holding on to them anyway.

You’ve Made a Large Life Change

Some of life’s changes require major wardrobe revamps. Your clothing needs will change drastically if you go from full-time student to banker, or from traveling salesperson to stay-at-home parent.

Your Clothes Are Trying To Escape

When your clothes start permanently congregating outside your closet (draping themselves over the treadmill, say), either you own too many clothes or something about your closet is so off-putting that you’re not even trying to put things away where they belong.

You’re Moving

Before you pack up everything you own, think about having to lug all those clothes across the country (or even across town). That should nudge you to be ruthless about getting rid of what you don’t need.

You’ve Moved To a Different Climate or Culture

If you moved without taking stock of your wardrobe beforehand, do it now—especially if your new home has different weather or social norms than your last place of residence.

You Have “Nothing To Wear”

It might sound odd, but the feeling of having “no clothes” usually strikes when you have too many of the wrong clothes or your closets are so stuffed that you can’t tell what you have.

Your Body Has Changed

Whether you’ve had a baby, lost or gained weight, or sustained an injury that makes once comfortable clothes constricting, you can make life easier by sorting through the contents of your closet and getting rid of what no longer serves your needs.

You’re Becoming More Minimalist

If you are thinking about exploring a more minimalist lifestyle or trying your hand at a capsule wardrobe, your current closet probably won’t serve your needs. An easy and fun place to start the process is by downsizing your wardrobe.

Your Priorities Are Changing

Whether you’re going vegan, protesting fast fashion, or wanting to live more simply, clearing out your closet so that your stuff aligns with your values can be a good first step.

You Need Some Cash

Is your closet stocked with unworn clothes or accessories in good condition? Host a tag sale, visit a consignment shop, or use a resale website or app to see how much your clutter is worth to someone else. Selling your used clothing is a great way to declutter your closet. Did you notice a theme within this list? Basically, you’ll know it is time to go through your closets and purge your clothing when you experience a change in circumstances, whether that is in your lifestyle, your work life, or even your family size.
