Can't decide

Michelle • I`m 24 baby Declan arrived 08/07/2017! I have 3 angel babies.06/18/15 and mono-mono twins on 06/27/16.
Which dress below would you were with what heels? I have three big events coming up and one of the good dress stores were going out of business so I bought three and I can't decide which one I would wear for which event. 
Events:
1. Valentine's Day
2. Our anniversary in May 
3. My bfs' movie premiere 
I was thinking the blue one for the movie premiere with the black heels with the sparkles. But I'm torn between the two pink ones for the other events. Ideas please!!
