Like a lot of people I was skeptical of purchasing a dress like this online, but after reading the reviews from others I decided to give it a go. I actually purchased two of these dresses as both my daughters are flower girls. Using the online size guide I found that both girls measured into the same size, trusting the guide I ordered them. The dresses arrived in fantastic time and are just divine, hard to believe they cost so little. Sizing, pretty much perfect, the dress for my younger daughter will need to be taken up, other than that the fit is great for both girls. I'm extremely happy and would certainly purchase from them again.
