This print looks best in two colors with a change where the smaller buttons start. High resolution recommended - I used 0.05mm Ultra Detail and 50% infill for strength (they're not just decorative - they need to hold your clothes together!)

Note - the four button button will be hard to use if threaded through all of the holes, so if you do want to use it, I'd recommend sewing through only the four innermost holes with clear fishing line to maintain the visual effect.
