Tu reviewers of the dress describe the item as the ideal summer dress. One shopper said: "A great throw-on dress! Very comfortable. Very cool. Drapes beautifully. Only worn it twice and on both occasions I was stopped by complete strangers to compliment me and my chic, elegant dress."
Another pleased shopper wrote: "Great Tu item ticking lots of boxes! 100% cotton fabric, so breathable (perfect for summer) loose and flowing but the drawstring sides give you a bit more shape for a flattering fit so it doesn't wear like a tent. Lightweight fabric so it falls nicely."
A third also praised the side ties, saying: "Comfy and elegant. Great dress. Flattering drape. Side ties make it flexible in style. Comfy and can be dressed up or down. I sized down as it fits a little big."

Customer Notes on Sizing and Fabric
Despite the praise, one shopper noted: "Lovely dress. I’m usually a 14 but the 12 was too big. Haven’t reordered as felt the fabric was too heavy for me." However, another pleased buyer shared: "The dress is really comfortable and flattering. The fabric is slightly heavier than I expected but great quality. I will get a lot of wear out of it. Total bargain."
