A present from abuela: fashion treasures

My abuela (grandmother in Spanish) got married in her native Uruguay in the late 1940's. She was 20 and literally a beauty queen. Last week sent me something very special: some of the items made for her on the occasion of her marriage - her trousseau.
Her mother Inés, who died a couple of years ago, still an elegant and graceful lady at the age of 100, was a master seamstress who, with her sisters, owned a chic clothes store in Montevideo, so only the most beautiful fabrics and exquisite cuts were used for my abuela's trousseau: glossy silks, fine lace, all impeccably crafted.
They are in pristine condition, and thanks to new trends in fashion, many have become perfect to wear not only to bed, but also outside, if paired with other, less revealing garments - the sheer fabrics are why I didn't model these clothes as I usually do.
One nightgown comes with a matching little 'jacket' (2nd pic from top: the nightie's cream lace trimmings; top left-side pic: the jacket). This jacket would be perfect with jeans and a black tee. I love the peach-colored muslin skirt with strips of black lace, and the knee-length buttoned silk white dress I'm dying to wear with a white tee and leggings or just shorts.
I'd love to hear your advice on how to wear these outside the house...
Gracias, abuela querida (and don't kill me because I disclosed information that will allow people to figure out your age...).
