Simple stripe-y summer dress

Although I love all kinds of complicated well-constructed dresses, vintage style and otherwise, there is another style I can't really do without: The simple jersey dress. I've made several different versions over the years but I think it is time for some more. 
The first fabric I want to use for one of those is this dark brown jersey with stripes in different colours. I think it may be a blend of viscose and cotton and the fabric is nice and solid and has good recovery. So, no weird issues I have to compensate for. 

I have about 3 meters of this stuff and I wouldn't mind having enough left for a top. Because the scale of the stripes is fairly large, I think it would look best if I used it in large, fairly uninterrupted pieces. And I think I should pay close attention to which part of the stripe pattern I place where.
I have been thinking about it for a while and there are some features I know I want, and some I am still considering.
The one unusual detail I want in this dress has to do with the skirt: Obviously, I like to match obvious stripes like this but I am considering a long dress and long, straight skirts (the only ones which can be matched nicely at the side seams) don't really work for me. So, I think I will cut the front of the dress as one piece and attach the back skirt to it, following the waist-to-hip angle. I hope the fabric is wide enough.

For the top, I am considering different options. Cut-on cap sleeves, normal set-in ones or raglan. Plain back, back yoke and/or some kind of cut-out. Straight waist seam at the back or one which follows the stripes. 
The options are in the sketches but could also be mixed and matched. 

I actually love the idea of a back cut-out but every option which has one also leads to more piecing at the back. If my fabric had simple even stripes in just two colours, I think I could make that work really well. But this is a colourful, busy kind of striped fabric and that makes me think I should keep things simple. With that in mind, I am drawn towards the first sketch. I'm still not sure about the sleeve choice though. The cap sleeve is nice but I also like the t-shirt effect you get with the set-in sleeve...
What do you think?
