Seeking Advice: Is This Outfit Modest Enough to Wear with a Hijab?

Salaam everyone! I'm a revert Muslim, and I'm traveling to Egypt in a few days. My family doesn’t know that I’m Muslim, and since I’ll be in a Muslim country, I feel like this could be a good opportunity to wear the hijab around them without revealing my secret (they’re not very open to other religions).

I’m planning to wear this outfit, and I want to stay as modest as possible. Would this outfit be modest enough to wear with a hijab?
