Hi. I definitely couldn't pass these dresses up. They are very cute!

I'm interested in getting 2 dresses.
1 Sweet Toss for Bella. She has 11.5" chest and is 11 in length, and
1 Watermelon & Strawberry Patch for Chloe. She has 15" chest and 14" length. Would her size be a problem? She is a maltese mix and might be too big.
Thanks!
