Organic Cotton V-Neck T-Shirt

I wanted a good quality white t-shirt to wear under cardigans and blazers at work, and after talking to a friend who raves about Eileen Fisher clothing, I thought I would treat myself to a really nice tee. I bought this one and tried it on in the evening and although the fabric seemed a little thin, I thought it would work okay, so I washed it and planned to wear it later in the week. I went to get dressed for work and it turns out that the fabric is so thin, you can see everything underneath it. I even put a white camisole under but it was so see-through, the round neck of the camisole looked weird under the v-neck of the tee. I knew that if I wore it, I wouldn't be able to take my blazer off, which wasn't an option I liked. I'm not sure what to do with this T-shirt now. Maybe I can use it as an undershirt, but I can't wear it alone.
