I don't know if this should be under the discussions and questions but I don't think too many of you check over there. But feel free to move this over moderators!!!
I've seen those who make the reversible dresses that close with buttons. Except that when you reverse them they look a bit funny where the button should go. I bought my daughter a dress a while back and it had buttons on both sides!
I don't know if you just didn't think of it but there ya go. Put buttons on both side and then your dress won't look odd. Let me know if you need pics!
I think you could put the buttons on before you sew the pieces together and turn it inside out because the buttons end up right on top of each other. Or maybe you could sew on 2 buttons at once.
Just my 2 cents! Happy sewing!
