I take my camera with me wherever I go, and I usually just dump it in my bag together with all my other things. I know, that's not a very nice habit. But it's such a hassle to bring an extra camera bag with me all the time! If you're looking for cute camera bags, though, the best place to go is CitySuper in Hong Kong.
Wasted an entire day in NY with my cousin, searching for the perfect camera case. Everything that we found were either bulky or boring. Went online (which I should've done right from the start!) and found a camera case, tailor made for my camera model. It fits perfectly unlike generic cases that will take up more space in your bag than necessary. Now, I don't have to worry about it being scratched inside my big bag! Bought the camera case from Amazon. Strap is from VLashor.
When unbuttoned, the case flips over and you can start taking pictures already. No need to remove the camera from the case! Genius.
