Free your mind, boost your confidence!

Do you spend some days worried that your neckline is a bit low or that your dress might be see-through?

Maybe you're a bit self-conscious of your upper arms or your knees and you'd rather they were covered up more?

Do you ever feel a bit uncomfortable in your outfit? Like it's not who you really are?


Are you comfortable smiling at strangers down the street or would you rather be invisible?


Did you know your outfit has the power to change the way you act?


At Cousin Billie, you'll find tailored pieces designed with careful thought and attention to detail.

You won't need to worry about all the little things, because we've taken care of them!

We don't accept “If I were 20 years younger..."  here!
