My sister and I both bought this dress to wear for the Disney Princess races, and we both found the the armholes are WAY too small. We are size 4/6, and got mediums. Though the dress fits great (not skin tight), we have to cut and open up the armholes, as they are cutting into, and underneath, our armpits. Other than that, the dress is great! Not too thin - will be perfect for a race!
The fit of the dress is a little strange (tight around the bust and waist and super super loose around the mid-section (fixed by a quick alteration)... but as a 33 year old who wishes I could wear princess costumes to Disneyland this is perfect!
I love it! A little heavy of a fabric which is great for when the wind blows you don’t have to worry about an accidental flash.
Super stretchy and breathable. Wore it for the very humid princess half marathon and had no issues whatsoever.
