12 basic wardrobe essentials for women

Declutter your wardrobe and restock it with these 12 clothing essentials you can find on ThredUp.

1. Black blazer 

Women’s blazers come in different fits, cuts, and materials, but one thing never changes: A black blazer is classic. This item is the ultimate multitasker because you can wear it for formal and casual occasions. 

Pair a black blazer with wide-leg trousers and black heels for a confident office look. On the weekend, layer it over a white tee and denim for something more simple. Depending on your personal style, a black blazer also looks great underneath a wool coat in winter. 

2. Trench coat 

You can’t go wrong with a trench coat for transitional weather. This outerwear piece is as elegant as it is effortless, especially for those windy and rainy days. Throw it over a knit sweater and jeans in fall, or wear it with a slip dress and sandals in warmer months. A trench coat in a neutral hue like camel or beige will match all kinds of items in your closet. 

3. Straight-leg jeans 

Straight-leg jeans are among the best denim pants for women. They’re ideal for casual but stylish looks and can be dressed up or down. 

For a business-casual vibe, style straight-leg jeans with a white button-up shirt and black heels. For a laid-back weekend outing, pair them with a graphic T-shirt and white sneakers.

There are so many jean washes to choose from, whether you prefer a crisp dark wash or a more laid-back medium hue. Find straight-leg jeans and other essentials for less on ThredUp.

4. White T-shirt 

A high-quality white tee is simple but indispensable. This wardrobe essential is a blank canvas you can wear with almost anything, from a black blazer to denim shorts and white sneakers. A white T-shirt is endlessly versatile, especially if you reach for one with a slightly fitted silhouette. Choose a fabric like breathable cotton to stay cool and comfortable. 

Pro tip: A classic white tee is one of the items you need to build a capsule wardrobe—a curated collection of clothing you can mix and match to create multiple outfits.

5. Little black dress 

The little black dress is synonymous with timeless style. This wardrobe staple works for everything from cocktail parties to romantic dinners. Opt for a sleek silhouette, like a fitted sheath or a classic A-line design, because these cuts are easy to accessorize for various occasions.

Wear an LBD with gold jewelry and black heels for a formal look. For something bolder, try colorful block heels and statement earrings. To dress it down, pair it with a denim jacket and ballet flats.

6. Wide-leg trousers 

Wide-leg pants are chic and flattering. Add them to your everyday wardrobe to elongate your legs and help you create sophisticated outfits that don’t compromise comfort. 

Pair these trousers with a tucked-in knit top and sandals for brunch with family. For the office, add a black blazer and heels. Choose pants in a neutral shade to maximize their mix-and-match potential.

7. White button-down shirt

A white button-down shirt deserves a place in every closet. This top offers endless styling options—it’s genuinely one of the most versatile pieces you can purchase. 

Wear a white button-down shirt with tailored trousers for client meetings and days in the office. Leave it open over a tank top and jeans for a relaxed, put-together look. You can also tie the shirt at the waist and wear it with a midi skirt. 

8. Knit sweater

A soft knit sweater is a cool-weather essential. It’s ideal for layering and looks more elevated than a crewneck sweater or hoodie. 

Wear it over a collared shirt for a preppy look or with a maxi skirt and boots for a feminine-meets-rugged outfit. A knit sweater works just as well with leggings or sweatpants, especially if you choose one in a neutral shade like charcoal or cream.

9. Midi skirt 

Midi skirts are adaptable and always on trend. These calf-length pieces work for all sorts of events and outings, especially if you choose a simple style and basic color.

Wear a midi skirt with a fitted tee and white sneakers for a casual daytime look. Dress it up with a silk blouse and black heels for an art exhibit or theater show.

This piece transitions well through the seasons. In fall and winter, you can wear it with tights and ankle boots. 

10. White sneakers

White sneakers are a footwear staple. Add these to your closet ASAP because they pair with almost everything, from jeans and a blazer to casual skirts and dresses. Choose a minimalist design for a simple aesthetic, or reach for a chunky pair if you prefer something more contemporary. 

Pro tip: Keep white sneakers clean so your looks stay polished and don’t fall flat. 

11. Layering tank top 

Women’s tank tops are layering essentials that help you build endless outfits. Choose a fitted tank top that hits your waist or lower in a basic color like black or white. If you switch up your look often, stock your wardrobe with several options in different shades and lengths. 

Wear a tank top under a black blazer for a polished work outfit, or pair it with wide-leg trousers and a lightweight sweater for a lunch date. You can also tuck a tank top into your favorite denim or a maxi skirt. 

12. Loungewear set 

No closet is complete without a matching loungewear set. Choose a long or short-sleeved bottom-and-top set made of a soft knit or cotton blend, which feels luxurious while still being cozy and breathable. 

This set is your ticket to comfort without compromising style. Wear it at home or, depending on the style you choose, out to run errands or grab a quick coffee with a friend. Loungewear has transcended its homebound roots, and we’re here for it.

Pro tip: Loungewear makes a great travel outfit.
