This never used, only tried on Reformation silk camisole with built in bra area lining is stunning in person. The dainty straps are A++. And the yellow tone is perfect for spring and summer. This is a true medium which is why it doesn’t work for me - if you are a S with a larger bust you could absolutely size up but if you have a smaller bust size I would recommend sticking true to size. Always from a smoke free home!
