This Is What a "One Size Fits Most" Outfit Looks Like On 3 Different Body Types

We've all encountered "one size fits all" or "one size fits most" labels on clothing, and it's understandable to be skeptical of these claims. No matter what your size, your weight fluctuates, meaning that some days your clothes might fit better than others. You might even wear different sizes depending on the brand or style of clothing. Then there's your body type — the most common types being oval, hourglass, triangle and rectangle — which also affects the way clothing fits your shape.

With all this in mind, can one size really fit all? Well, with the help of body-positive supermodel (and the original plus-size supermodel!) Emme, we're putting three products to the test.

Three of our viewers (a size 2, 6 and 10) with three different body types (rectangle, oval and hourglass) tried on three different clothing items, each of which claims to be "one size fits all" or "one size fits most."

Serena says she is normally a size 2 and Emme says she fits into the rectangle body type category.

"The waist is less than 25% smaller than the shoulders and the bust — it's straight. This is really rectangle, where it's square and the waist is slightly in," Emme says.

Jackie says she is usually a size 6 and Emme says she fits into the oval body type category.

An oval body type usually means that your "shoulders and hips [are] equal [and] the hips are about six inches smaller than the chest," Emme explains.

Marguerite says she is a size 10 and Emme says she fits into the hourglass body type category.

With an hourglass figure, "the waist is more than 25% smaller than the shoulders," Emme explains.

"There are variations, and of course when you go up and down in size you're going to be a little bit more exaggerated in different ways," Emme says.

So, here are the three clothing items that the three ladies tried out:
