Dedicate a day to driving around finding unique shops, walls, fields of flowers, free parks, restaurants, plant shops etc. that fit your particular brand. There are also plenty of blog posts about the cutest walls in Austin!
I absolutely love shooting at open-roof parking garages where you can see downtown Austin. I always head to the top floor, preferably on weekdays, when people are typically not parked on the last floor. Garages offer privacy, great lighting, multiple textures especially for streetwear looks.
