Beyonce is the latest celeb to launch into the athletic clothing brand with her Ivy Park named for her daughter Blue Ivy.

Bey has said the the 228-piece collection aims to promote a powerful message of self-assurance, confidence, inclusivity and diversity, the cornerstones for a generation reared on mindfulness – and it is democratic and accessible.

According to reports, Beyoncé found it depressing that up to 80 per cent of girls give up sport at the age of 13, thus why the line caters to young girls and has a slouchy and comfy aesthetic but with style. The brand was launched in collaboration and partnership with TopShop.

Within hours of the release in April, the brand sold out.

The collection ranges in price from $15 to $265, according to the Topshop website. Here are our fave pieces.

Actress Kate Hudson is a co-founder of Fabletics, which launched in October 2013.

The line is sold online exclusively. Shoppers can purchase individual items or join a VIP membership for lower pricing and outfit recommendations. Hudson has said of the line that she hopes that Fabletics will inspire women to embrace a healthy lifestyle. “That was a huge goal for us, to inspire women to empower themselves by getting active and taking care of their gorgeous selves, not as a fad or a quick fix, but as a way of living that promotes health, community, determination, passion and joy,” she said.

These pink and grey Fabletics leggings run $75 retail.

The Fabletics Salar Space Dye Capri runs about $65.

Grammy-award winning singer and brand new mom Carrie Underwood launched her athletic clothing line CALIA in 2014 while expecting her first child.

The brand was first available at Dick’s Sporting Goods retail stores and then started selling online last March 2015. The name is inspired by the Greek word for beauty, “Kallos”, as well as calla lilies.

CALIA’s collection includes mid-range priced capris and pants, tops and bras as well as accessories such as tote bags, headbands and water bottles. Functionality and design were key; some pockets in CALIA gear were optimized to fit smart phones.

These Essential Printed Panel Capris runs for $70.

Her women’s Essential Fitness zip up Jacket is a big seller perhaps because of its slimming effect. It has wicking technology pulls moisture away from the skin and boasts a rapid evaporation time so you stay dry, cool and comfortable. It’s just $75-$85.
