It’s not the all-white outfit that makes my eyes burn. Not even the wrinkles on the jacket or that whole “I’m not a girl, not yet a woman” vibe.
What really makes it a poor, miserable choice for a casual date is the lace blouse/something-under-the-jacket-piece, the too-short, lacy tights (meant for girls), the socks & flats combo as well as the mix of lace and cotton.
A simple pair of jeans would have worked wonderfully with the jacket and bag.
Weird doesn’t suit everybody.
