where can i get cosplay costumes

Also looking to get a nice lightsaber, but I don’t feel like paying $400. Their boots were too expensive for my taste, captain america adult costume so I’m still looking for a decent quality brown boot. I decided against making mine because I would just end up sewing my hands together. Edit: If you’re decent with a sewing machine you can literally make your own Star Wars stuff fairly easily, it just takes time.
