I saw a link to this '70s era dress on the blog A Beautiful Mess and looooove it. Of course it sold on Etsy right away. It doesn't seem like it would be that hard to sew, but a pattern would be very helpful! I'd probably want to sew it in cotton knit instead of polyester, so an exact fabric match isn't necessary there. Any suggestions?
Eliminate the ruffle and you've got it in this pattern: http://butterick.mccall.com/b5320-products-3161.php?page_id=1185 and on sale too!
Though this pattern is for an actual wrap dress and lined...... so you might want to look for something else.
