Rash Guard Swim Set with Bucket Hat

Unisex (we used for our daughter), and sooo cute, this set has a rashguard, diaper cover and matching bucket hat with shark & crab details. In size 6-9 months, (the hat says "up to 9 months"). From Child Of Mine by Carter's. I noticed it kinda looks like some red has run at the neck, but I keep checking and I think it's just the red hem on the inside showing thru, and also reflecting off of the white. There is some cracking on the shark design of the shirt from washing/age.. See pics. Last pics of my kids wearing as baby's.
