I don't think any of those items are that special. I'd wear the black dress, but I wouldn't buy it, because non-exclusive or otherwise, D&G is too expensive for me. Chalk it off the list of even remote possibilities. Hell, Ann Taylor is too expensive for me. I would make a dress like that, if I needed a dressy black dress, but I already own two black dresses that I like a lot (one vintage 1950s wool for winter, one contemporary, stretchy/springy lycra tee-shirt affair for summer).
I wouldn't buy the off-shoulder top because I don't find them comfortable. I have wide shoulders, and the necklines of those won't ever stay put on me--they tend to sproing upwards whenever I move my arms.
The bluejeans I wouldn't buy either. Firstly, I don't wear skinny-leg bluejeans. My legs are too thick and muscular, so they never fit, and even if I do shoehorn into them, I look like I am perambulating about on a pair of indigo sausages. Secondly, I don't like light-blue denim. Thirdly, I am sure they are way too expensive for me. $50 is the outer limit I would even consider paying for a pair of bluejeans, and you can usually get a decent pair of reliable, classic, Levis for around $30.
