What Do You Think of ... These Two Evening Dresses?

OK, so these No Minimum Free Shipping codes paired with random nightly website updates must stop RIGHT NOW before I loose it. I love these codes too much because if I see a popback in my size I can go to the checkout right away, without looking for other stuff to add to my cart and get the free shipping (while loosing the coveted popback in the meanwhile). I know that it sounds crazy but I think that I even had a Jcrew-induced case of insomnia TWICE last week. Like I would wake up (for any reason) around 1 am and then I wouldn't be able to fall asleep again because my brain was unconsciously pumping adrenaline in my veins to keep me up for the site update. Of course by the time that the update (something like 6 am) really took place I was sound asleep and I actually woke up even later than usual.

Anyway, one morning I was at my computer early enough to snatch up a Brynn dress in warm wisteria for the quite incredible price of $39.99. I had tried it twice in a 0 in the evening primrose print but something was off with it. Then when it went on sale I tried it in a size 2 in the warm wisteria color and liked it better but it was a little bit loose in the bodice, so I made a mental note that as soon as the price would come down a little bit more I should order a 2P. Well, I wasn't expecting the price to go down from $99 to $39.99 but it took me less than 30 seconds to acknowledge the new price, see that the 2P was one of the few sizes still available, put it in my cart and check it out (thanks no minimum shipping code number 3).

I was almost sure that I would get a cancellation email but it did ship, and it wasn't even broken or stained, just a little bit wrinkled.
Now I think that it's a beautiful dress but I'm wondering if it's too short or too young-looking for me? Basically I like it but, am I going to wear it? I know, how could you know? But in your opinion where could I wear this dress to? I have a wedding coming up but it's in MAY next year and I'm sure that I'm going to use the excuse of the wedding to buy me another dress in the spring. Those of you who have this dress, did you wear it so far? I think that the evening primrose print is more easy to dress down for a drink or evening out with friends or even the office (with a jacket), while the solid colors are more "occasion" or party dresses.





Should I keep it and just wait for the right occasion to wear it or return it? Keep in my that I paid the price of a tee shirt for it.

A few weeks ago, on the aftermath of my wedding outfit dilemma, I started to look for a "any occasion" black dress to have just in case and I bought this simple Zara dress. At that time $59 sounded like a good price. I liked that it has a timeless shape, without being a sheat dress. It's a lace overlay pullover, with an elastic band at the waist. Kind of classic-classy, but not a fun dress (at least without accessories - and I can't think of anything but pearls with this dress):




It is surely more wearable than the Brynn dress and I think that I will get more wear out of it but I'm also less excited about it.
I understand that these are two completely different dresses but I don't feel like keeping both. Which one should I keep in your opinion (if I should keep one at all)?
