I need help sangat ji!

Wjkk wjkf sangat ji! I am a married man and love my wife tremendously, however, I feel that our spirituality levels are very different from each other. I'm not saying this out of hankar (pride), but I take sikhi more seriously than my wife does. She sometimes wears clothes that go down to her lower stomach barely covering it but when she moves around, she shows skin. She told me that when she wears clothing, it is okay to show her bra strap. Yes, it's her body and it's her choice but it is not modest doing it. I feel like sikhi would question this. Am I overreacting or is this something that should be taken seriously? Thank you! Wjkk wjkf!
