About Alexandra:
Alexandra Suhner Isenberg had somewhat of a fairy tale fashion education. She pursued it with a passion, studying in three countries and learning everything she could about design.
Although she had studied the height of haute couture, it was a humble nightshirt that caught Alex’s imagination. While high-end clothing lines were everywhere, she knew the same people who wanted high quality clothing needed something comfortable, modest, and luxurious to sleep in!

The resulting business, The Sleep Shirt, is a perfect example of how niching WAY down can help you build a more successful brand! Rather than creating an entire line of options, Alex started with one basic garment that she worked hard to perfect for the specific customer she wanted to serve.
Another important takeaway from Alex? Some of her brand’s biggest successes have been possible because she reached out to her network! She knew what she wanted, and she reached out to the right people until she made it happen.
