This costume is perfect! We're doing a group of Waldo's/Wenda's. We all (men and women) got this costume and the girls are wearing skirts with the Wenda socks. They DO run big. I am 5'9-5'10 and around 155 lbs and a woman with a semi slim build. The small/medium is a perfect fit with a small bit of room. The LG/XL is just that. Large! I had read a review that 'the shirt was a Lg and the sleeves an XL'. I will totally agree. Perfect for an average man but not at all for a average woman. It looks like a sack...haha. Great quality shirt, glasses and hat. The shirt is actually SOFT not itchy like some costumes. Can't wait for Halloween!
