I think they both look great. It doesn't seem as if you should worry about looking slimmer in either of them to me. #2 shows off your curves more, and the color is more alive.
I don't know where the not appropriate for church comments are coming from, they both look great to me.
I definitely prefer #2. It shows off your slim waist and the colors look great for Easter. You look very cute, by the way! Oh, and from the other thread you're definitely not a 34band! You could very well be a 28F or there about. Check out the blog Invest in Your Chest. Cheryl is a 28F for comparison.
They both look great on you, but I prefer #2. I'm a big fan of purple, plus that top make the girls look great! And I gravitate towards brighter, lighter colors for Easter - like a visual reminder that spring is coming...
I don't like #1 at all. To me it hides your body and just hangs there. #2 is the better fit on your body (make the girls up top look great!) and shows off your waist. The white also compliments your skin tone well. It's also more "springy". #1 looks like a great winter outfit when paired with some leggings and boots... but not for spring IMO.
I like both but I think I like the dress the best. I'm just find of that style. You could find a big belt to wear high and show off your curves more? I also am not crazy about the white and purple together even if it is more springtime.
I think #2 is best, colours are always better!
Plus, #2 shows off your body better. Wear what makes you feel good though. You look good in both of them, I just like #2 better
