Cute Options Junior's Pintuck Blouse with Embroidery

I was looking for something to wear instead of a t-shirt and this shirt works nicely. It's longish; for me it's just this side of too long. I had a bit of problem with sizing. The first shirt I bought was a medium, but when I bought another color, the medium was too snug for my taste across my chest and shoulders (I'm 43, 5'6.5", 120 lbs, 34C). It seems like the plum medium was mismarked and should have been marked large. Unltimately, I bought larges because I prefer to be comfortable but the mediums would work if you don't mind snug. The trade-off is that the large has almost too much material below the bust, sort of maternity style, but since my tummy doesn't stick out I don't have to worry that someone's going to ask if I'm pregnant (at least I think not?) The material is ok; the colors are a bit faded like it's an old favorite and it's soft enough; but it's probably too casual to be considered a blouse for the office. If I were looking for something to wear to the office, I probably would have given this 3 stars.
