Dress Ilyna wore at the bachelor parties
Ilyna wore a sleeveless dress with a simple pattern of diagonal stripes. There were two wide straps crossing over her shoulders, and the small V-neck goes barely an inch below the middle of her collarbone.
It looks a little uncharacteristic for her, and she was a bit insecure about overestimating the formality of Vasquez' party. She still wore it at Jason's party, however.
