2021 Trendy Online Fashion

The world of fashion is no longer dictated just by what models sashay down the catwalk in each season. There’s a new mover and shaker in town: social media. Online trends - fashions that go viral on apps such as Instagram and TikTok - are big fashion news. Here are eight of the hottest trendy online fashions that have been going viral in 2021 and how you can recreate them.

Structured coats with loungewear

2020 was the year we all fell in love with tracksuits and joggers, and now online fashion influencers have been taking it to the next level by pairing their tracksuits with a great structured coat. Look for coats that match or complement the color tone of your tracksuit, and keep it slightly formal with double-breasted or long peacoat styles. Posh Fashion Boutique’s A Solid Woven Blazer Jacket would make a great autumn piece and looks fabulous styled over a navy tracksuit. Throw on a pair of chunky tennis shoes and a cap to really nail the look.

Head-to-toe pastels

Perhaps inspired by the current love of all things '90s and early 2000s, cute yet chic has been a big viral trend. This one sees fashionistas pairing pastel hues with… more pastels. Imagine pastel pink pants with a pastel purple sweater vest or cute lemon cropped trousers with a pastel floral shirt. The possibilities are endless and will also see your wardrobe boosted with some great separates that will work across the seasons.


Maybe it was the fact we were all looking for something to do at home, but tie-dye has been a huge online trend. Tie-dye has been making waves on everything from jogging pants and hoodies to t-shirts and cardigans, as well as accessories and even yoga pants. Grab your own slice of the tie-dye trend with this Tie-Dye Blue and Orange Print Hoodie Top from Posh Fashion Boutique.

Basics with a twist

There’s been a big move toward basics but with a little added extra. Think shoulder details, cutouts or reworked straps. Instead of reaching for a simple black racer vest to team with jeans for an easy daytime look, why not add a touch of fashion flair with a one-shoulder detail top instead, or rework your night-time look with a basic top but with added cutout details?

Big floral prints

Large flower patterns have proven popular online lately and aren’t quite as terrifying to wear as they may sound. Try wearing a bold floral piece with simple separates. For example, you could team a bright floral skirt with a simple black top or a bold floral shirt with a pair of jeans. Why not try a bold floral mini skirt with a crisp white shirt? You don’t have to be head to toe in florals, so if you do want to embrace the trend, check out this amazing Blue Floral Print Tacked Flowy Maxi Skirt from Posh Fashion Boutique.


Another viral online look has been androgyny, with boxy, masculine blazers being styled up with everything from biker shorts to skinny jeans and jogging pants. Baggy suits and straight-leg pants are also proving to be popular, along with bomber jackets and chunky trainers.


This year, you can’t escape the trend for all things crochet. Step forward, Harry Styles, who helped catapult crochet back onto the cool list when he sported a colorful chunky crochet cardigan for an appearance on The Today Show. This rocketed on TikTok, inspiring people to pick up their crochet hooks and try to make their own. You may not want to be quite as bold as Mr. Styles, but subtle crochet details are a nice nod to the trend. This sexy Black Floral Crochet Spaghetti Strap Hanging Top is an easy take on the trend and would look great styled under a blazer with jeans and heels for a laid-back night-out look.

Bright pops

Fashion is bouncing back again after the pandemic, and bold, bright colors have been a big online trend. Add a splash of color to an all-black outfit with a brightly colored blazer or team a fluorescent top with a pair of black pants. If you’re not feeling that brave but still want to take on the trend, do it with your accessories. A great pair of color pop heels, an eye-catching luminous clutch bag or a stack of brightly colored rings can all help lift your look and add a splash of color to your outfit.
