Beware the shrinkage
Size: X-Large, Color: Chill
This shirt came looking as expected and the quality was good but it ran a bit small. I had to give it to my dad and it looks great on him!

NOT EVEN CLOSE ON SIZE!!
Size: XX-Large, Color: Light Blue
I'm not a small guy...im rather robust like a good Italian dressing..and this shirt is 100% disproportionately wrong! If your thinking 3xl sounds good for the price DONT BUY IT!! At best this is an XL t-shirt with a 3XL tag. I can't return it because I immediately cut tags off my shirts..I know weird right lol. Anyway hopefully you read this and like ex-relationships you 'MOVE-ON'!!!!!
