I have special needs so, please read my review.
Color: White, Size: X-Large
Edit I decided to wear it inside under my clothes as a liner, it shrank too short so not it is uncomfortable to tuck in after I hand washed and dried on delicate until half dry and hung. I will start for anyone that need a soft first layer try this shirt, it fits nicely and it doesn't pull under my arms, I have larger bust measurements compared to by rib cage. It is soft out of the bag and first wash came out nice ,( hand wash) The shirt is a perfect thickness for me! I loved it so much, EXCEPT for the inner arm seam, I so wish the arms were seamless, it was painful for ME, I have Fibromyalgia and this felt like torture by the end of the day, this was too bad for me because otherwise the shirt is GOLD. Buy the shirt I am going to try to scrub the seam and see if I can soften it up a bit . Maybe this company has a seamless version, I would love to know this.. I cannot comment of durability and washability,

My favorite undershirt with boleros & crop tops
Color: Black, Size: Small
Not overly thick or thin - it’s just right for staying warm and wearing under crop tops and boleros. Form fitting but not uncomfortably snug. Great quality! I now own 3 and might get one more since I bought a bunch of new crop tops and boleros.
