Tiny wrestler Big Muscles!!!!
My son puts on this muscle shirt and instantly transforms into a mini WWE superstar. He flexes in the mirror, challenges the dog to matches, and insists on wearing it to the grocery store like it’s a uniform. The muscles may be fake, but the confidence is 100% real!

Grown women here - bought this for a Halloween costume and it is perfect! Sleeves are a bit short but it doesn’t affect the overall look.

Good Enough
My son is 10 years old. We got the size of 10-12. He chose this himself, after he tried on, he enjoy it. It looks like exactly the picture. It is cheap made as I expected with the price, but it satisfy the purpose (use only in Halloween a couple of times). The only suggestion I have for the manufacturer is: leave the sleeve longer, the parent can cut them to fit.

Cute and funny
It was perfect for my son’s kindergarten class. It was what he wanted to be when he grew up and this is what he wanted to be and it was great.

We made it work
We bought this for our 9 year old son to wear as part of his Sampson of the Bible costume. The sizing is off. We read reviews that said it ran small, so we ordered the size Large (12-14) and it fit our son perfectly, and he normally wears an 8-10. The inside is very scratchy and itchy, even the sleeves, so he had to wear a long sleeve shirt underneath. When it arrived, the muscles were pretty flat, so my wife had to open the stitches and add more stuffing. It wasn’t an easy task and it took her a while. You can see the difference in the first photo...the right side is before she added stuffing, the left side is after. When she got done with it, it looked pretty awesome. For what we got, and the work we had to put into it, we think it’s overpriced.

So much fun!
My son got this to dress up as a festival attendee! :) The sizing was spot on. The material was a little itchy on his skin. It definitely was a crowd pleaser!

Buff suit
My son was so excited for this buff suit he loves costumes and really wants to have big muscles one day… this suit fit him perfectly… the material is thin but super durable so he doesn’t get hot in it… he like to layer shirts over the muscles
