What Are Style Essences?
Have you ever noticed that some people look effortlessly sexy in a tight dress? And others look incredibly cool in skinny jeans and leather jacket? Some people look fierce and others look totally innocent. All of these descriptions are style essences.
A person's essences describes their looks or what kind of beauty they communicate. Because there isn't just one type of beauty. Beauty comes in many facets and each style essence portrays a different aspect. Depending on the style essences you have, certain looks will emphasise and highlight that kind of beauty in you.
And there is a simple reason for this: clothing that follows the natural lines of your body and face (your overall appearance) will look harmonious on you. Whereas clothing that doesn’t respect your lines will look disharmonious or odd.
So we could also say that style essences or style identities are the natural lines and shapes of your face and body repeated in clothing. This is not to be confused with the traditional ‘fruit’ body shape theory. That theory is concerned with achieving symmetry in your silhouette. Style essences are about repeating the natural lines of your body in your clothing to achieve a harmonious look.
To demonstrate this better, let’s look at an example:

This is when Beyoncé wears her lines. She looks stunning and her clothes look like they're part of her.
And this is Beyoncé when her clothes don't respect her natural lines:

This is not a question about how beautiful Beyoncé is. It’s simply about how much she looks like herself in clothing that follows her natural lines of her body vs. clothing that doesn’t and therefore looks odd or unnatural on her.
Beyoncé's look is sexy. It's what her physical appearance communicates. So any clothing that does not portray this kind of style looks odd on her.
Let’s look at another example:

Above Lady Gaga when she respects her lines and below Lady Gaga when she doesn't:

Again, this isn’t about beauty. It is simply about the kind of clothing that looks harmonious on Lady Gaga (unconventional perhaps, but that’s just Lady Gaga). The point is that the clothes don’t look separate from her. The flouncy dresses might potentially fare better on Beyoncé, but they don’t work on Lady Gaga at all. She doesn’t look like herself in them, and she looks separated from her clothes. In contrast, the oversized, straight-cut garments that look so foreign on Beyoncé compliment Lady Gaga beautifully.
And that makes sense because Beyonce’s body and face are curvy and soft, there are no straight lines or harsh edges. Consequently, straight clothing breaks up her feminine roundness - it's like trying to fit a square into a circle.
With Lady Gaga it's the other way round. Her appearance is more angular and straight with sharper edges. Clothing with round shapes and soft silhouettes won't fall nicely on her, as she doesn't have the curves to fill them. Lady Gaga's natural appearance doesn't communicate sexy or girly. It communicates boldness, intensity, and danger. That's what makes the suits look powerful on her.
Both ladies are beautiful, but they look their best and like themselves when they wear their lines.
