Hello Sophia and welcome to the Cow Audio Forum.
You don’t say where you attach the lavs. The placement may be part of the problem and how you rout the cable back through the clip. I always use a 2″ squared piece of G-tape to secure the mic cable inside the garment. It keeps things looking neater and also damps clothing and body rub.
Normally, boom mics locked down just out of frame (very close to the interviewee) sound better than lavs. But not always. The lavs you have should work fine. Be aware that the cardioid lavs have to be very carefully placed because they are directional.
It sounds like you need to find quieter places to do your interviews.
