Bought at 5/6 for my niece. I asked my daughter to try it on someone who wears a size 4 and it turned out to be a tad too big. This barrel is true to size. This dress is actually more beautiful than in the picture. I will definitely order more.
Pros
Got for Easter for my 2 year old daughter. She was beautiful in him and she felt beautiful in him. Exactly what I expected.
Cons
The sleeveless style may not be suitable for colder weather.
