What to know before you buy plus-size business casual attire

What is business casual attire?

Business casual attire includes comfortable yet professional basics, such as blazers, sweaters, slacks and skirts. Tops that fall into this category include blouses, collar shirts or knit tops. These pieces usually are paired with clean, simple footwear such as low-heeled shoes, flats or boots. There’s some flexibility when it comes to jewelry, although it mostly includes classic pieces with a modern spin, like pearl studs, small hoops or simple necklaces.

Machine washable vs. dry clean only

Before you purchase a piece of business casual clothing, decide how invested you are in taking care of it. While a lined wool blazer is an elegant essential, it’s one of many pieces that are dry clean only. As a result, you’ll have the ongoing cost of getting it professionally cleaned.

There are countless options for easy-care, machine-washable clothing. Many polyester blouses and slacks, for example, are line dry. Some of them are wrinkle-resistant, so you won’t need to spend time ironing or steaming them.


When you buy clothing off the rack, there’s a good chance you may need to tweak it for an ideal, custom fit. Getting clothing altered isn’t the cheapest service, but it makes a world of difference in the fit of certain pieces. For example, a tailored blazer fits better around the shoulders and small of the back. Taking up the hemline of longer pants prevents them from dragging on the floor.

What to look for in quality plus-size business casual attire


Plus-size business casual attire is available in sizes 14 and bigger, as well as sizes 3X and bigger.

Many women find a better fit with number sizing when it comes to slacks and skirts. Additionally, several bottoms following number sizing are available in different inseam lengths. Only some high-end blazers and tops are available in number sizing.

Other garments use progressive sizing, such as 3X. Fit is often hit or miss with these pieces, especially for wearers who are between sizes. Other wearers note it’s common to experience size discrepancies across brands that use progressive sizing.

Popular materials

Business casual attire usually is made with quality materials that retain a “new” look wear after wear. Several affordable pieces are made with polyester and stretch materials such as spandex, Lycra or nylon. Not only are these fade- and shrink-resistant, many of these garments are less likely to wrinkle.

More expensive pieces are made with premium materials such as wool, cashmere, silk or lace. These materials look and feel luxurious, and there’s a noticeable quality difference between them and cheap imitations. They withstand the test of time better than pieces made with more affordable materials.


Well-made business casual pieces such as blazers and skirts usually are lined with thin, lightweight materials including silk, satin or polyester. Linings create a neat, smooth foundation behind heavier shell materials. Additionally, they make garments easier to slip on and take off, including over base layers like blouses or hosiery.

Colors and prints

When choosing business casual attire, you may feel torn between solid colors and prints. There’s no need to stress over which is better to buy; instead, choose solids and prints that coordinate well. Many professionals invest in a few solid pieces, such as a navy blazer or black slacks, that are easy to match with printed tops.

How much you can expect to spend on plus-size business casual attire

There are several plus-size business casual staples, such as slacks and blouses, that cost $25 or less. Pieces that are made and cut better run between $30 and $80. High-quality blazers and slacks made with premium materials may run as high as $100-$300.

Plus-size business casual attire FAQ

Do you need a blazer, or can you wear sweaters?

A. Many professionals wear sweaters instead of blazers, provided they fit well. Simple sweaters are recommended, although there are many striped, argyle and floral styles that are considered acceptable. You can dress up sweaters with brooches or skinny belts.

What type of bag should you match to a business casual outfit?

A. Structured totes remain a top choice for their simple, practical designs. Their clean, crisp lines also complement outfits as opposed to overpowering them. However, if you’re looking for something smaller, a classic top-handle or frame bag is ideal.
