I do love this dress, it is perfect for summer as it is very easy to wear. However , I suggest sizing down, they fabric is very stretchy maybe 50-100% give. One slightly annoying thing is that I find the neckline facing not large enough to stay inside - it is about 5cm deep and creeps out - it either needs a deeper facing or a really narrow one with an extra line of stitching (may do this myself) but it really is just a minor annoyance.
Great for summer - professional enough for work but casual and comfortable too. Ordered size large, and I'm usually size 12-14 (US).
