Sorry my previous post had errors, including the sizes; kindly refer to this one: This dress is EVERYTHING! Appears EXACTLY as pictured! I'm between a "XS" (for stretchy tops/dresses) and a "S" (for non-stretch). I went with the "XS" and it fit like a glove! Has a lil stretch to it. Not too much. Not like leggins, so it won't be as forgiving if the size you pick is wayyy smaller. The bra part has such a nice shape to it (instead of lying flat on the bust) so it doesn't make us small girlies up top look flat chested at all hihihi;). If you're slender with a bigger bust I feel there's enough room in the bust area and this would fit perfectly👌🏾.   Also, the top part fits quite snug but comfi, but not as snug at the bottom. For reference, I'm 5'8, 60kg, flat tummy, toned, slender, w/ the smallest bust ever (32 A/B). So if you're debating between 2 sizes, and you choose to go w/ the smaller option, note that the top could be a bit hard to zip up if you're pear-shaped or heavier up top, so you might want to stick to your true size for non-stretch material. FN ATE DOWN with this one! Also being 5'8 (172cm) I'd say it got to right under my knee cap, perfect length for this classy red-carpet ready fit. The pearls were intact when I received it too! This dress looks EXPENSIVE, thick material that gives quality, LOVE IT!
