Practical fringe growing-out advice

I am helping with the hairstyles for a local early-2000s stage show. We have basic costumes and need a few recognisable styling details. I have been collecting references for avril lavigne hairstyles but I want a manageable stage interpretation rather than an exact celebrity copy. Our singer has long hair and wants to keep the existing cut. A low side part and a couple of tiny braids seem achievable. I am unsure whether the smaller details will read clearly beyond the front row. There will be a short rehearsal, so we can test the shape in advance. We need a method using basic hair accessories rather than specialist pieces. The singer moves around quite a lot during the performance, so we also need the style to hold together without constant adjustments between songs. Which styling details communicate that era most clearly in a small live performance?
