LO's summer wardrobe is getting really tough to put together! I am on the hunt for some good shorts for him. He is 18 months old, tall and skinny. However, most of his height is in his torso--his legs are kind of short. So most shorts seems to hit too far down on the leg for him. I"m looking for shorts that hit right above the kneecap and have a slimmer fit. I"ve tried Old Navy 12-18 months and they're too long and a bit too big in the waist...Gap same thing. Thanks!
