Part of what drives me mad about the homogeneity of high fashion models, is that, even ignoring the racism, sizeism, ableism, etc etc etc (which is a huge problem, obvs.), it’s just artistically boring.
Half the time, the designers use aesthetics as an excuse for choosing 28 size zero pale white women for their show. Don’t come to me with an excuse about aesthetics. If it’s just about aesthetics, why does every single show use models with the same body type/skin color/etc despite having huge variety in clothing design? I understand that you might occasionally, as a stylistic choice, want a show where all the models are identical. Maybe the show has a dystopian, conformist vibe. But how can that be the right choice for every show, every year, year after year after year?
Fashion is suppose to be about creativity. Using identical models is like insisting that all painters/calligraphers/illustrators use the same texture, color, size, and style of paper. Of course they’ll still be able to create masterpieces, but there’ll always be a level of artistic expression that’s constrained by their choice of canvas.
TL:DR Not only do most model choices reinforcing harmful beauty standards, but they’re honestly lazy, dull, and uninvented. If you want your work to be thought of as art, prove you have a creative bone in your body and branch out a little.
