"私が始めた頃にはプラスサイズというものはありませんでした"

Simplified Meaning:

Years ago, when someone began their career in fashion or acting, clothing for larger body sizes wasn't common or recognized. Imagine trying to buy clothes, but the store only sells small sizes. It can feel very frustrating and unfair. For instance, think about trying to find a dress for a special event, but the store doesn't have anything that fits you because they only cater to smaller sizes. Back then, people with bigger bodies had fewer choices and often felt left out. Today, more brands make clothes in all sizes, allowing everyone to find something that fits, feel good about themselves, and participate in fashion. If you're dealing with a situation where you don't feel represented or included, it's important to keep pushing for change because progress happens when people advocate for diversity and inclusion. Just like how the fashion industry eventually responded to the need for plus-size clothing, other areas of life can improve too when we speak up for what's missing.
