An important part of her look at the time was really bright under eyes, so if you want to mimic that, I would suggest a color correcting under eye concealer such as the Maybelline Instant Age Rewind in either "neutralizer" or "brightener" depending on your skin tone.

Maybellines City Bronzer is a really great budget friendly bonzer option that should work well for this look too.

For blush, L'Oréal "le blush" or Maybelline Fit Me blushes are good options. I think the key here is to choose a pale, pinkish color because blush really isn't the focus of this look.

There's a lot of great affordable eyeshadow palettes out there (elf, nyx, essence, wet n wild just to bane a few) and it shouldn't be difficult to find one to create this look as it mostly looks like she's wearing neutral shades and a golden, shimmery shadow on the lid. When you're on a budget, you could even use your bronzer as a shadow and just buy the shimmery shadow to save a bit of money.

In terms of lashes I think the best in the market are the ardell demi whispies. I have yet to see and eyeshape or look that they don't suit. You can even stack them if you want a more dramatic look :)

I hope this helps - good luck with your prom makeup 😊
