Her first design will be a top, which will be sold exclusively on her lifestyle blog 'goop'.
The 40-year-old actress says she decided to design the top because she could never find such a thing anywhere, reported Examiner online.
"I have always wanted a one shouldered exercise top and could never find one so we've collaborated with Beyond Yoga to make my dream top," Paltrow posted on her blog.
"Made from a luxurious high-tech fabric for active wear Supplex, this one-shoulder cami is great because it is quick drying and offers stretch without stretching out, keeping in shape even after a workout.
"Subtle monochromatic quilting adds stylish detail to this soft yet durable top," she added.
