For today's Tip Tuesday, I've created two little "What to Wear" boards for ya'll (I was born and raised in Ohio, but, for some reason, I sure do love a good ya'll once in a while!)  The first example is for an older brother/little sister sibling set, but I'm really just trying to show what I mean when I say "coordinating without being too matchy." 

Pieces from this set can be found at...
Gymboree (Girl's dress, bracelet, & shoes; Boy's shoes)  
Gap (Boy's shirt)
Old Navy (Boy's pants) 
Carters (Girl's flower clips) 

The second example is for a casual outdoor spring session for a family of four.  This would probably be best for late spring here in Ohio, due to the short sleeves and all.... 

Pieces from this set can be found at: 

Gap  (Mom's Shirt, Jeans, & Sandals; Boy's Jeans and Fedora) 
Banana Republic (Mom's Necklace)
Old Navy (Dad's Shirt; Boy's shirt & shoes; Girl's dress and shoes)
J.Crew (Dad's jeans)
