First date outfit? ok for a 21 yr old?

so im going on my first date on saturday, just a dinner and movie thing. i was thinking about wearing a brown 3/4 sleeve shirt w/pearls and dark jeans w/brown pumas. is this ok? i definitely want to be comfortable and we may be walking a lot, so i'd be more comfortable in sneakers than flats and i dont wear heels. so any suggestions or comments are welcomed.
