Combining sexy styles with comfort and self-affirmation is a goal that some in the fashion industry are struggling to achieve. It's also one that several celebrities have made it their mission to accomplish. After Rihanna and Kim Kardashian, it's the American singer Lizzo's turn to stand up for a more inclusive approach to fashion through her own brand of shapewear designed for (absolutely) all body types.

If ready-to-wear brands regularly claim to be rethinking their business to propose inclusive clothing, it's still fair to say that curves don't get the same treatment as slimmer physiques. Simply step inside the stores of the most famous brands, and you'll soon notice -- with a few exceptions -- that the sizes of dresses, suits and other stylish pieces rarely exceed XL or XXL, far from representing the whole population.

Stars make a stand

Whether with Savage X Fenty or Fenty Beauty, Rihanna has been striving for several years to smash all the codes, conventions and stereotypes relating to body shapes, sizes and skin color. It's a strong message, and one that's in total harmony with the values of the Barbadian singer. Since the announcement of her pregnancy, she doesn't hesitate to step out in outfits each more glamorous and sexy than the next, determined to change the way people view and think about maternity clothes. It's an initiative that clearly appeals, given the success of the two brands, which have helped show the way to other celebrities keen on making fashion more inclusive.

Nearly three years ago, it was Kim Kardashian who made a name for herself with her wildly successful shapewear brand, Skims, also aimed at all body types. The former reality TV star turned businesswoman quickly extended her range of sculpting apparel to underwear and loungewear -- always in a (very) wide range of sizes -- before extending the concept to swimwear. The line was launched in March, and stocks are often close to depletion.

Here again, the idea is not only to offer swimsuits suitable for all women, with bodies of all shapes and sizes, but also to make them available in sizing options to fit the greatest number of people, from XXS to 4XL in this case. For Kim K. there's no reason why women shouldn't be able to find the right fit just because of society's idealized body shape.

"An opportunity to be who you are"

Now, it's the singer Lizzo's turn to promote inclusive fashion with Yitty, her own shapewear brand, channeling body positivism and self-affirmation, and officially launching April 12. It took several years to develop this label, which is now being launched in partnership with Fabletics. It promises sculpting designs that can be worn as underwear or outerwear -- the choice is yours -- and which are by no means intended to go unnoticed. Not content with offering sizes ranging from XS to 6XL, the star chooses vibrant colors that catch the eye and assert curves rather than hiding them.

"This is a love letter to my big grrrls, and a welcome letter to Every Body. This is *not* an invitation to change who you are... this is an opportunity to BE who you are on your terms. I don't know about y'all -- but I'm sick of people telling me how I'm supposed to look and feel about my body. I'm tired of discomfort being synonymous with sexy. [...] @YITTY isn't just shapewear, it's your chance to reclaim your body and redefine your beauty standard," Lizzo said in an Instagram post.

If initiatives of this kind are still few and far between in the fashion industry, women can now count on world-famous ambassadors to help change mentalities, push things forwards, and pulverize the tyranny of an (all too) long idealized physique.
