Are you struggling to create a fashion line with garments that don't go out of style? You're not alone. The fashion industry is incredibly fussy when it comes to ever-changing trends and styles, so there's no telling how soon your apparel line will become obsolete.

But rest assured, there are ways to maneuver these erratic waters and still come out on top. Research has shown that global sales of online apparel and accessories are expected to reach $765 billion, so if you play your cards right, you might see an increase in sales. Here are some fashion pieces that are likely to stay in style.

Trench Coat

Whether you're marketing a modest, casual clothing line or a sophisticated, evening style, this piece can easily fall in either category. Designed by Thomas Burberry, trench coats are an intentional global fashion icon often donned by several celebrities like Blake Lively, Victoria Beckham, Meghan Markle, and the Olsen Twins.

The best part is that this piece looks classy and chic, and it's also inherently functional, protecting the wearer from the cold, wind or rain. It can keep your clients warm and allow them to move with ease. Adding a trench coat to your clothing line is bound to get attention since it looks good on everyone and can be adjusted with any other garment.

Whether it's paired with a t-shirt and jeans, an attractive dress, buttoned up or open, it'll look swanky for any occasion, combining trench coats with sneakers for day events and heels for a night out.

Denim Jeans

Whether you're marketing for the winter season or spring, denim jeans are one of the few apparel pieces that won't disappoint you in the least. This piece is one of the most reliable garments as it stimulates year-round interest. Even if the most innovative trends are featured on the runway, jeans will still stay in style throughout the four seasons.

Whether your clients need an outfit for an office dinner or a casual shindig, a daytime picnic or a dinner under the stars, jeans can work for any occasion by simply substituting accessories and footwear.

Black Heels

You may have heard the phrase when in doubt, wear black. This piece is an essential closet item that looks feminine, alluring and classic. You can't go wrong by adding a pair of black heels to your fashion line, especially considering it can easily transition from work occasions to a night on the town. With the right accessories, like diamond jewelry or an ankle strap, black heels offer a sleek, elegant look that will stay in fashion for decades to come.
