Agreed, costume. Though Boba Fett can be one of the most challenging!
My learned experience has been that the focus, size, expense, duration, or quality of a Star Wars merchandise-based collection can vary wildly, but I came to feel that in the end, it's just you and a bunch of stuff. Which you mostly don't even want other people to touch, haha.
People costume for different reasons, but much of those orbit around the core idea of interacting with other people. When you open yourself up to that, the world is waiting to be discovered and in a great way.
A Boba costume is great. Girls in slave Leia bikinis will pose with you for photos. Kids and drunk guys will know your character immediately and yell the name. You can watch the world from under your dark visor. Fellow Fetts and other costumers will share build experiences and tips with you. Go to conventions, see how many people want to take pics with you. If you choose, you could join the 501st or other groups and do public or charity events for fun.
Boba is popular enough that you'll find many options to use kits, completed/commissioned parts/paints, used parts, or your own scratch-builds however suits your time, interest, funds, and skills.
Over time, you will need, learn, and even pass along some skills in building your costume. You don't have to be perfect to start with, no one here was when they began. My first 'adult' Star Wars costume, years ago, was an x-Wing pilot, had a cardboard chestbox with taped on pieces of Sharpie-colored paper. Man it hurrrrts to finally share that in writing, haha, but I know others here have similar stories so it's ok.
Seriously, though, I believe you'll find costuming infinitely more rewarding in many ways for a long time, and I hope that happens for you. Best of luck!
