Turning thrift finds into an online resale clothing brand – tips?

[alex]

Hi everyone, I’m Alex and I’m in the middle of turning my love for thrifting and vintage into a small online resale clothing brand. I focus on curating wearable secondhand and vintage pieces, taking my own photos, and writing detailed descriptions so buyers know exactly what they’re getting.

Right now I’m trying to figure out the smartest way to grow without burning out or wasting money. For those of you who run small online shops (clothing or otherwise):

What channels gave you the best early results (social, marketplaces, your own site, forums, etc.)?

How do you balance time between sourcing, listing, marketing, and customer service?

Any mistakes you made early on with pricing, shipping, or branding that you would avoid if you were starting again?

I’d really appreciate any practical advice or real experiences from people who’ve scaled a side project into a stable online shop or service.
