2 year ann. date night dress?

H • 🌎🌙🌈🌿
so i just bought this dress last night but i really want to wear it for when my boyfriend and i go out to dinner to celebrate our 2 year anniversary - but i'm wondering if the dress doesn't suit this occasion? any feedback is helpful!(: 
oh, and i attached a second picture bc you can't really see the fabric up close in the mirror pic. 
thanks in advance y'all!
also, ignore the bright blue and pink, i was in my little sisters room because she was sewing it for me lmao
