Graduation Dress

Hi everyone! I (24F) am attending my boyfriend's graduation at the end of June. I tried on a few dresses last night and I am absolutely stumped as to which one to go for!

I think I will definitely keep the coral one as it was only £25. Currently torn between wearing the coral, rust, or green dress to the ceremony. I think the yellow is ruled out as, although it is also lovely, it clings slightly to my stomach and doesn't give me as much shape as the others even when wearing shapewear. Happy to hear differing opinions though.

Thank you! 🙂
