I've had my renee tunic in natural for over a year and it's great! Perfect for layering with a corset, but also quite versatile for day-to-day wear.
In "natural", it's quite sheer and can't be worn without something over it. The off-white colour pairs really well with most of my wardrobe and I wear it year-round.
I've lost 25lbs since my purchase and the size L still fits fine because it's quite adjustable and meant to fit loosely. I've since purchased the renee in 2 more colours in size M and those also fit quite well, so no need to stress too much over the size chart.
I machine-wash and -dry mine in a garment bag. It comes out of the machine quite wrinkled, but that doesn't bother me and I prioritize convenience. Even with my neglect, it's holding up great!
