Before you do anything, you should probably search, “SHOULD I add pockets to a dress”. I believe I mentioned in the linked thread that many female items would look terrible with pockets. I mentioned that none of the dresses that Cheryl Scott (ABC 7 weather at ten) wears have pockets and would look terrible with them.
In the movie, “Gunpowder Milkshake”, there is a scene depicting the high school aged Sam in a diner. She is wearing a cute sweater but, seemingly patched on by a bad tailor with terrible eyesight, there is a pocket that looks absolutely horrible. It is a perfect example of what I mean.
