Don't know if anyone here sells on Poshmark, but they just sent out this announcement today:
We are launching the ability to shop and sell fashion for kids and men.
With any expansion comes both excitement and uncertainty, and I wanted to take the time to address some questions that have arisen on the platform: The Poshmark you know and love will remain the same. When you update the app, you will find that we have kept the core experience simple and unchanged. All you have to do is choose your shopping interests—Women, Kids, Men—to personalize your Feed experience. You can choose to integrate those interests or to keep your interest solely in women’s fashion.
