My fav casual look is jeans and a t-shirt. However if you are not careful you end up looking like James Dean in the 1955 movie Rebel Without a Cause. (JAMES DEAN MADE THE WHITE T-SHIRT COOL) Not exactly the feminine differential you were hoping for.

Here is a great Goldielocks look - Just right:
On Amazon the above two: "Neineiwu Women's Loose Casual Short Sleeve Chiffon Top T-Shirt Blouse". They come in two dozen variations of colors and patterns and will not break the bank at $24.99. As always with Prime - free shipping and easy returns.
The material is semi-transparent chiffon, which is a feminine differential being thin and flowy. There are two layers, that will keep your bra from showing and a soft elastic hem at the bottom that allows you to blouse it around the waist. it is very forgiving as to size and flattering to the middle body. The short sleeves are a loose bat-wing design which allows the sleeves to drape down the arm.
I purchased the "Leopard Print" to go with a camel skirt and tan pants I have. The white blouse I purchased for my daily jeans look, but sure I will find other combinations ore dressy.
Always look for the feminine differential. It adds to your escape confidence as you transition for a overall male look to a feminine appearance. No surgery required.
