1. Lululemon

Lululemon started its company as a staple yoga clothing brand but soon expanded and became a leading company in the new industry of athleisure wear. It's known for its classic black "Align" leggings but it doesn't fall behind in constantly releasing new fashion-forward athleisure clothing.

Each type of legging is made to perform different activities such as yoga, running, dance, and many more. There is also a rising popularity in outerwear. Jackets, scarves, and sweatshirts have seen new releases in anticipation of the holiday season. Rapidly expanding, Lululemon ending the quarter on July 29 with total sales rising 25%, per Forbes.

It's still a small company at nearly one-tenth of Nike's size but the expansion is only beginning. Lululemon stock hit an all-time high in early September and doubled its profits last year. So don't get bored with your sport's bras and leggings because more is in the works for Lululemon.

2. Gymshark

Take 2 minutes to scroll through Instagram and I bet you will find at least one Insta-athlete wearing Gymshark. Gymshark has taken the world by storm and put a fun twist on athleisure wear. The UK brand focused solely on social media marketing and invested in popular Instagram fitness influencers.

The initial 18 influencers had a combined following of 20 million people. Something was done right in this millennial marketing strategy because Gymshark successfully TRIPLED sales from July 2017 through July 2018. My personal favorites from the company are the Energy Seamless collection and the Ombre Seamless collection.

They are both fun, stylish, and make me strive to get my workout in everyday!

3. Alo Yoga

Alo Yoga takes the cake for the most fashionable out of all of my suggestions. They adapted the term 'Yogalosophy' which is their mission to "bring yoga into the world." Not only did they bring yoga into the world but they brought it to Gigi Hadid, Ashley Benson, and Taylor Swift who are some of the many celebrities sporting the brand.

Their popular lace-up leggings give a fun twist for your next yoga class. The "Alo Interlace Leggings" retail for $108 but are raved to bring a sexy vibe to the gym.

4. Mello

I always like to acknowledge start-up companies that I'm keeping my eye on. Mello is a new athleisure company that's mission is to help you purchase "Leggings you'll have forever." Their promise is that upon purchase of a legging, they will always replace them for any reason at any time.

They call this the "Forever Promise," to replace any legging that is ripped, frayed, pill or become damaged in any way. Sounds like a good deal, right? I highly recommend to invest in their Forever Leggings that retail for $78. Visit the website at https://wearmello.com
