This is the Wyota Maxi dress from Lilly Pulitzer.
A few notes:
This is an XL
It is VERY stretchy material so this also means it is slightly clingy.
It would be maternity friendly IMO
I'm not personally a fan of the tie neck or the high neck
There are cups inside the lining of the dress no they do not provide "support" so I do recommend still wearing a strapless bra (I'll tag some of my faves)
I am 5'7 and I have on a small gold heel with this dress for length reference.
