Child has body odor and will not listen to me

Help. I just recently noticed my 8 year old daughter is starting to have body odor mainly at her arm pits. She takes well I make her take a shower/bath every other day. I even asked her if she is washing that area and she said yes but how true that is I’m not sure. I tried to talk to her about it but she got so upset and embarrassed she wouldn’t even look at me. I told my husband/her father and asked maybe he could talk to her and he said she’s fine leave her alone. For one I am a firm believer in good personal hygiene also she is starting 3rd grade next week and I would never want my child to go to school and have body odor just for the principal of it but I also don’t want her getting made fun of. Any suggestions?
