this product is awesome! I have it in three colours (black, white, blue) and I believe it's perfect to use as an undershirt or even on its own. I personally use it as an undershirt with various of my sweaters - as the lace perfectly pairs with most clothing items, and also just makes everything look... even more pretty! one thing I noticed that could be a con is that sometimes the seam on the lace will gather up into small fabric balls and come a bit undone, but other than that, I think this product is amazing. I find it to be fairly high quality, along with being extremely comfortable. this shirt can truly be worn anywhere and everywhere, as it's intricate design can be seen as fascinating and fashionable enough to be worn to maybe even a fancy occasion, while the comfortable material can comfort you to sleep or even when you're lounging around. truly a piece that's a staple for me!
