About us
Emma Coster started with a single small boutique and one big desire: to help people shine in what they wear. Not by following trends, but by listening. By understanding. By truly seeing who you are. Her sharp eye for quality and genuine advice quickly built a loyal community of women who dared to be themselves.
At Costerline, it’s about more than clothes. It’s about that moment when you look in the mirror and think: “Yes. This is me.” It’s about the rush of confidence that runs through you when something fits perfectly. Emma believes fashion isn’t superficial—it’s daily empowerment, a form of self-love, a way to stand tall.
As Costerline grows into a brighter, more modern space, Emma remains hands-on in every detail. From carefully curating each piece to creating a space where you are truly seen. A space where you feel free to explore, to play, to shine.
For Emma, clothing is never just clothing. It’s a chance to claim yourself. To show the world who you are. To feel confidence like you never have before. That’s what Costerline offers—every single day.
