Apparently Target has been selling Isaac Mizrahi wedding gowns on the site for a while now. I never knew. They are phasing them out and the dresses are half price. The two above have very happy reviews. On the left is the Strapless Sheath Dress for $45 (the sash is sold separately and apparently no longer offered on the site). The dress on the right is the Silk Faille Trapunto Bell Dress for $80 which has a hem detail that is difficult to see in the pictures but reviewers praise it.
[not to self: if you come across it again add the link to the Target wedding gown that somebody had a dressmaker add some detail to, it was lovely]
