I love love the simplicity (but not boring) of the t-shirt dress at Marc Jacobs. Wearing it with those sandals give the outfit a touch of elegance. 
3.1 Phillip Lim's rosette dress is one hot item this summer. It sold out really quickly back a few months ago, but who can blame the customers? The dress is like a fusion of many huge SS07 trends, including the LWD and the 3-D rosettes. 
I don't know if this dress by Marni counts as a T-shirt dress or just a shift dress, but it's still very 'this season' looking. 
House of Holland is supposedly all the rage these days, but I absolutely dislike these super eye-catching slogan shirts (and possibly because I'm not a fan of Aggy, who is always seen related to this brand.)The only unfortunate (or fortunate?) thing about this trend is that it's so hard to actually find them in stores, esp in high street stores.
I like the sketching of a girl on this Stella McCartney t-shirt dress, but I don't like the slanted shoulder design.
I'm not sure if this is a t-shirt dress, but I do like all the not-obvious details. The tailoring looks amazing, although the price certainly reflects the quality. (By Helmet Lang)
I've been staring at these dresses by See by Chloe on NAP for quite awhile, but never had the courage to splurge on it because I've never seen it in real life and have no idea if it would fit on me. I love the giraffe pattern one (left). But can you really wear them without wearing micro-shorts or a slip underneath? Oh ya, just to avoid confusion, wearing a huge, oversized T-shirt is not a t-shirt dress. A t-shirt dress, as you can see from the examples above, are cut like normal t-shirts on top, and are extended to be a dress. So the shoulder area should actually fit you.
