costumes....costumes....which one is suitable for our main character?

how am i going to decide the costume for J.Lo; our main character that handle by Addreana? which one is suitable for her...
i have searching for a few costumes for her....but still don't know which one to decide for her...
and...for dilla...a pregnant girl....the size is not the problem...but its about a choice to make it real....
recently our group costume have discussed about the cloths and accessory for the actor and actress and we also have our proper practicing timetable....hopefully i can attend it although i have been busy with my final year project and proposal presentation that will be coming this saturday...
wish me luck, guys!!!
i think i'm going to put the picture of the costume that i've mention above...so that i can get your comments on it...
