Help Wanted

Well Dear Readers, I need your help. I am on a quest for a pattern for this style of 40s apron dress, sort of like the kind pictured above. You know, the kind that buttons up the back, has a big sash waist, and ties in the back. I have searched both etsy and eBay with not much luck. I did find one pattern on eBay, but it is a 30 bust. Way to small..... especially to try and grade up.

So, I would like to ask all you vintage seamstresses out there if you have a similar pattern I could borrow or if you know of one for sale. I need about a 40-42 bust, since I am kinda busty, although those pointy vintage bras do wonders in hiding a large bust, at least on me they do! I would rather grade down than have to grade up, if at all possible.

I really appreciate any and all help!!!!! :)
