Women's Serena Mini Sundress

I am 5’4 and 110 llbs with smaller chest size and when I saw this supposed “dress” at first I rechecked my order on Nordstrom because I thought I accidentally ordered from a children’s wear brand. The sizing is on the smaller side but the material is thin and the straps can be adjusted which is fine. What is not fine is the length. I am by no means tall. I usually get petite in all clothing bc I am short and generally mini dresses are not mini enough. But this. This can be worn as a top on me, I’m wondering what it must wear like for taller girlies and people w a bigger chest. Cute in pics but no idea how it looks relatively longer on the model. I think it would still be considered a tunic even if I were in 6th grade or something
