Honestly, I’m thrilled with this darling blouse! It’s a great classic option for work or an occasion but super simple. If in between sizes, size down. I’m in a small and it’s great. Steams beautifully. I’ll wash it cold and lay it out to dry. Front is lined. Back is not but it’s not see through. I have it tucked in fully. I sized down 1 to a 28 in the jeans. True size 8 in the sandals
