I would say that if I had bought this shirt in my normal size, it would have been too small- I ordered a full 2 sizes up based on the manufacturers measurements and it fits fine. I purchased the largest size available (XXL) simply because I have VERY broad shoulders (17" across shoulders, 40" bust, 34" waist), so of course this means the sleeves are baggy on me, but I think that's kind of cute and also gives me a bit more shoulder space- the short sleeved would not have worked for me for this reason. The shirt is a bit sheer, as chiffon usually is, so you'll want to wear some type of undershirt- either white or to match your skin tone. Make sure you're buying from the maker, Etosell, and not a knock-off. Theirs is over all pretty high quality and nice looking, even the neck ribbon/bow. The fabric is breathable, lightweight, and comfortable, nice to wear even in the hot summer.
