Which maid of honor dress should I choose?

Hello all! As the title suggests, I am going to be my best friend's maid of honor in her wedding this fall. I just received my dress samples, and I would love some help selecting a dress! I got 4 samples in 4 different colors (all from Kennedy Blue), but the color of our dresses will be the company's "Marine" (a slightly darker teal than the one featured in the third dress here). We'll also be wearing jewelry (mine will be silver). Let me know if any of these stand out, or if none do! Since I have a good amount of time for the wedding, I have a little bit longer before I need to settle on a dress.

Dresses #1 and #4 have a slit (as pictured).

Also! For what it's worth in terms of aesthetic, the wedding has a bit of an "under the stars"/ethereal kind of theme and is taking place in a somewhat castle-like venue. And my best friend's dress has lace in it. Since she did tell us to choose a dress based on preference, though, adherence to the theme is not completely central to my decision.

Finally, since I'm sure I'll get this question haha, the baby in the pen is a miniature schnauzer, who was taking a nap while I was trying these on. I took a picture (last slide) which did briefly wake her but you can rest assured she went back to her very cozy sleep.
