I was taught that for very lightweight fabric you should self-interface using the fashion fabric of the main garment. If you really don't want to do that you absolutely must test a remnant with sample interfacing and see how it's changed, both before and after washing.
Back in the day when I made a lot of shirts with fusible interfacing, I always interfaced the bit that wasn't seen, eg, the inside of the collar stand or cuff, or the underside of the collar, because of the problem of the interfacing glue seeping through.
