The '90s fashion revival is one of the most talked about industry trends but, as is often the case when it comes to fashion, there's more than one style in vogue.

While you've probably seen the resurgence of tracksuits, graphic tees and hoop earrings, one fashion trend you might not be familiar with is the rise of modest fashion.

True to its name, modest fashion can roughly be described as dressing in a relatively covered manner with longer and looser clothes, without compromising on the latest style and colour trends.

Here's where modest fashion came from, how it's grown, and advice on how to rock the look.

Where modest fashion came from

While primarily associated with Islam and the requirement of Muslim women to cover up, modest fashion can be seen throughout many different time periods and cultures.

The trend can be traced back as early as the eighth century Islamic Empire. Then there's the robes, shawls and intricate kaftans of the 14th century Ottoman Empire. Even the Farthingale skirts of Elizabethan England could be considered modest fashion.

Fast forward to the 21st century and RMIT University lecturer Shazia Bano describes modest fashion as "a struggle to find a mediation between traditional modesty and blending into the crowd".

As Ms Bano explains, modern modest fashion emerged from small-scale online retailers.

Now modest fashion has been endorsed by global fashion brands and retailers, launching their own exclusive modest fashion lines and embracing modest styles in many of their collections.

The trend has even featured in international fashion shows, including London and New York fashion weeks.

"Making fashion that accesses both sides of the audience is the real trend that's going on right now," Ms Bano says.

With modest fashion searches increasing by 500 per cent on Pinterest in the UK, and more designers resorting to longer and more flowy designs, the industry is expected to increase 51 per cent by 2019 and reach a net worth of $450 billion.

Modest fashion in Australia

In an Australian context, modest fashion is only starting to take off, according to Tarik Houcher, the 29-year-old CEO of a hijab fashion house.

Inspired by his sister's inability to find "hijabi-friendly" clothing, Tarik and his family opened one of Australia's first modest fashion clothing brands only six years ago.

Tarik explains how opening a modest fashion business in Australia hasn't been an overnight success because it was a completely new concept for the existing fashion market.

"One of the biggest struggles has been pioneering everything," Tarik says.

But starting from scratch also provided Tarik with a clean slate to work with to differentiate his brand from traditionally simpler styles associated with wearing the hijab.

It wasn't until Tarik and his team ventured into newer and brighter patterns, designs and colours that modest fashion in Australia really went viral and "changed the hijab world" here, he explains.

"Before then, no-one wore floral. We released this really feminine pink floral collection and it went viral and everyone loved it," Tarik says.

Since then, dozens of other modest fashion boutiques and online stores have opened to accommodate this new gap in the Australian fashion industry. And a modest fashion show was held in Perth earlier this year.

The trend was even recognised by the Department of Foreign Affairs and Trade who created a "Faith, Fashion, Fusion: Muslim Women's Style in Australia" exhibition at the Islamic Arts Museum in Kuala Lumpur.

Ms Bano believes the exhibition really "started the conversation on modest fashion in Australia and made a statement that it was there".

Social media has played a big role in modest fashion’s growth

Over the last few years, the fashion industry has noticeably improved its cultural diversity, with models like Duckie Thot, Imaan Hammam and Halima Aden.

As a result, for many Muslim women, dressing modestly has become a creative form of self-expression where they can explore current fashion trends and mould them to create a more modest look.

Many inspiring young women use Instagram to document their own take on modest fashion and personal style, and encourage other Muslim women to explore modest fashion's infinite avenues.

Nineteen-year-old Instagram influencer Nawal Sari, from Liverpool in Sydney, started wearing the hijab at the age of sixteen when the modest fashion scene in Australia was barely existent.

"I looked up to my mum, my aunties and my cousins, and it was all very plain 'mum' clothes. I just didn't know what I was doing and I thought loose clothes and a tight hijab was the right way," Nawal says.

With the rise of social media as a platform for fashion and beauty bloggers, Nawal, who's had an interest in fashion from a young age, built her own style by taking inspiration from bloggers she would see on Instagram.

"I made an Instagram account a year after I wore the hijab, after I begged my mum," Nawal explains.

"I would see other girls overseas in the UK and America wearing jeans and a nice outfit, so I tried it.

"I never mainly looked at hijabi bloggers in the beginning — there wasn't many — so I was looking at normal bloggers and their outfits and making it my style."

Today, Nawal's modest twist on street style has helped her reach over 50,000 followers on Instagram, inspiring more than just a Muslim audience.

"I'm wearing sneakers and more street style, and everybody likes it. It's not just the Muslim community," Nawal says.

For 21-year-old hijabi model Miski Omar from Auburn in Sydney, who also started wearing the scarf at the age of 16, her style when first wearing the scarf was "so basic".

"I would just wear an outfit and chuck a slip-on scarf on top. It was very messy. When you first start wearing the scarf it's a lot of trial and error," Miski says.

Like Nawal, Miski took inspiration from those around her, regardless of whether they were Muslim.

"In my first year of uni, I saw this girl wearing flared pants with Chuck Taylors, and that was not something I would see back at home in Auburn or at school. I thought, 'That's so cool, can I wear that?'" Miski says.

From this, she grew to build her own personal style where she mixes "many different subcultures that I find cool" to create her own unique bohemian edge on modest fashion.

"Today, wearing my hijab is my expression and it's me being free," Miski says.

When it comes to advice on how to dress modestly, both Nawal and Miski explain there's one all-important trick you have to master first: confidence!

"Don't be afraid. If you see something, just try it, see if it works, test yourself. You really will be surprised as to what could work," Miski says.

Just like with most fashion trends, the trick is to take your own creative characteristics and weave them into the clothes you wear.

Don't let the fear of looking different or being the odd one out deter you from exploring how different shades, textures and cuts work together. Instead, aim to be the trendsetter.
