I just found a picture of Sarah Hyland, and I love every single detail about it! In my opinion it is a really glamorous dress! Also I extremely like her hair and her makeup. It looks really natural and casual.
Further more I believe it would look far better if she was wearing ombré hair. Another point is that violet lip color, it really fits her in this occasion. In addition the neckless she is wearing perfectly matches with her dress. As well the high-hells are really fetch and the kind of give the outfit some color.
In conclusion I think she is a really nice girl, beautiful and a great actress!
