See through shirt

Do you think it’s wrong of me to wear a see through shirt cause my boyfriend didn’t like it.

Now let me explain this shirt it’s a girls baseball tee. It’s in that style and the sleeves are like a red orange and the rest is white. Now when I look in the mirror you don’t see anything, all you see a bit of my black bra poking through. I don’t understand why he got upset cause it’s not form fitting it didn’t show off anything all that you can see is that I’m wearing a black I don’t know if a nude bra would be better but I don’t have any and I thought black would’ve been better than any other color.

Any opinion ladies
