Putting snaps on Tzitzit

Shalom rav,
I had a pair of wool tzitzit and i was wondering if it would be a problem to place 2-3 snaps along the sides so it os easier to wear and stays on me better. I remember seeing somethin in halacha about the beged needing to be mostly open. Does that mean completely open- or just that a small thing like a snap holding it together wouldn’t be a problem.

Thanks!

No problem with putting snaps on the sides.
