My first order had a hole in the blue and white stripe.  You didn't see it until it was stretched out.  I returned then and repurchased these plus the argyle since I have a feeling that was a very random hole.  I received the next set and they were perfect!  I love these leggings and they helped my  son discover and play with his feet and legs. Definitely a must have for your baby.  They are a little long for 3/4 months but that's nice since he won't grow out of them for awhile.  They still hold to the thigh but I like to cover his heels while leaving his toes out.
