They were apparently discontinued. Which it unfortunate, because they really were amazing. I haven’t used any other drugstore cream/gel eyeliners, but I would recommend MAC blacktrack fluidline if you’re willing to try something outside of drugstore brands.
The dress is pretty in-your-face, and I feel like a more subdued look would go well with it. My first instinct would be to go with a fairly simple eye- though maybe with slightly dramatic eyeliner, maybe false lashes if you’re comfortable with them- and a pink lip.
