Best and most flattering dresses for hot temperatures?

[Yoyoyo1]

I'm late 40s, size 12/14, 5 foot 6".

Bump

Loose, linen, cotton, or cheesecloth

I have some nice ones from me&em over the years.

Thank you

I bought some ankle length (I'm 5'8) pure cotton dresses from Aspiga which are perfect in hot weather. Hung them on hangers after washing and could wear them without ironing.
