Recently, as more people have been preferring a clean, straight shoulder line like Jenny’s square shoulders,

inquiries about shoulder fillers

have also been increasing.

However, square shoulders are not determined simply by shoulder width alone,

and are often influenced by the clavicle angle, trapezius line,

and overall upper-body proportions as well.

Today, I’ll explain why Jenny’s square shoulders are mentioned so often,

and

the directions of change that can be considered with shoulder fillers.

  1. Why Jenny’s square shoulders are mentioned so often

Recently, as the preference for a slim, well-defined upper-body line has continued, interest in square shoulders has also been rising.

Jenny’s square shoulders

In particular, the expression Jenny’s square shoulders is often used

when referring to a silhouette that flows neatly from the collarbone to the outer shoulder line.

Jenny’s square shoulders

Rather than looking excessively wide,

many people prefer the feeling of the neck line and trapezius line connecting naturally,

so that the upper-body proportions appear more refined.

Also, when wearing off-shoulder or sleeveless outfits,

the overall impression can change depending on the collarbone line and shoulder angle,

which is another reason related interest continues.

  1. How the square-shoulder look can differ

Square shoulders are

not determined simply by shoulder width alone,

but are often influenced by skeletal structure, clavicle angle, and the degree of trapezius development.

For example, if the trapezius is well developed

or the shoulders are rounded inward,

the upper body may appear more rounded.

rather than the actual neck length itself,

the neck line can look longer.

Conversely, when the collarbone line is visible

and the outer shoulder line connects in a relatively horizontal way,

the neck line may appear longer.

  1. The direction of changes expected from shoulder fillers

Shoulder fillers may be discussed when considering changes to the upper-body silhouette,

while补lying volume to a shoulder line that appears sunken.

In particular, if the outer shoulder line appears to drop sharply,

or if the connection below the collarbone does not feel smooth,

related consultations may take place.

Left) Before, Right) After

Some people say they noticed changes in how their clothes fit

or differences in the mood of their neck line after the shoulder line was refined.

However, using fillers does not mean that a specific celebrity’s line will be created exactly,

and the appearance can vary depending on the existing bone structure and muscle shape.

  1. Why volume and design are important

Rather than simply using a large amount of filler,

the process of setting a design direction that suits the current body type can be important.

This is because even with the same amount,

the line can look different depending on the clavicle angle, shoulder length, and trapezius shape.

Also, the design direction can vary depending on the left-right balance and upper-body proportions,

so a plan tailored to the individual body type is often considered important.

Recently, rather than simply wanting broader shoulders,

many people prefer a silhouette that falls naturally and neatly.
