This is a great little suit and my son looked so handsome in the wedding.  I bought an 8 since my son, who just turned 6, wears a 6-7.  The suit was big on him. Bigger than the size 8 suit he tried on locally but not so much he couldn't wear it.  I had it altered in a way that I hope to let it out and he can wear it for his 1st Communion in a year. The zip tie was broken - off track - when we received it but the company sent me a replacement very quickly.  I would recommend this suit.
