another vote for the 1st dress!
i think second one looks more like an actual wedding dress in a smaller size, while the first was made specifically for a little girl
ooh! and definitely go for a bigger size in the dress..i was a bridesmaid in a wedding in march, and they ordered the completely wrong size dress for me (3 sizes too small!!!) so needless to say, a lot of work had to be done....and it ended up looking completely different from the original dress. would have been a much easier fix if it was a bit too big!
