I bought this for my son's 12th birthday and got the small in navy. He is 5foot5 inches, solid and plays rugby, and my husband said he'd never wear it!! How wrong could he be!! Ha ha!!
If I manage to get it off him to put it in the wash I'll be lucky--- he loves it!! He even takes the dog out for a walk in it, changes into it the minute he comes home from school, and even threatened to wear it to school on the next non-uniform day!!!!I'm now considering getting another one so he can alternate them.
Just a quick note on the sizing- it comes up long in the body if you pull it down, or pull it up and have a baggy middle. Strange!! But my son opted for the long body and slightly baggy legs, which then means the crotch is halfway between his bottom and his knees!!! But in my opinion, it only adds to the hilarity of the outfit especially when he struts around the lounge to 'gangnam style'!!!
All in all, a definate thumbs up.
