This is what I would buy!
Jeans:
Dark wash long & lean (pretty self explanatory!) -- http://www.gap.com/browse/prod.....pid=673950
I'm personally a fan of their Limited Edition collection (most of my jeans are these)
I have this pair:

They're dark wash jeans with two cute pockets with bronze buttons on the front (not side pockets), and the same pockets with bronze buttons on the butt pockets. They're really comfortable and look dressy with the right top! I wear these to work often.
I am itching for a pair of grey jeans, and these are nice:

Not sure what size you wear, but there is a pair of long and leans but only in a size 20 on sale for $21.99! They are also dark wash but with a bit more distressing.

The boyfriend sweater is a great basic piece. Just a simple v-neck, but you can definitely dress it up and there are many great colors to pick from. The fabric seems luxurious too. My favorite colors are the jay blue (which is a bright turquoise, reminds me of a pretty peacock) and the orchid blossom (a dark pink bordering on purple... the color sort of reminds me of a rose wine. It's a hard color to describe but very feminine and reminds of me floral things. It's not pale though... it's a vivid shade.)
I have this sweater and love it:

It's a simple quarter length sleeve sweater with a few cascading ruffles on the chest. I have the orchid blossom color. It's almost like a maroon in person.
I couldn't find the wrap dress you mentioned!
