I came up with an outfit i like but i'm scared that its out of fashion?

Ok so tomorrow is church and i don't know what to wear. Our church is casual but dressy. I was thinking a white and yellow striped long crop top with a tank top under. Then the tank top would be tucked in these shorts that have a soft feeling but have tiny denim looking stripes on them. Lol its hard to explain. Then i would have a brown belt. Does that sound ugly or would it be cute?
