Can’t be beat for the price
Size: XX-Large, Color: Blue
Can’t beat it for the price, I was at super fancy NYE party. Lots of guys in very expensive jackets asking me where I got mine, this jacket got tons of compliments and looked great in photos. Quality was higher than I figured it would be for this price point. Go one size up, I am normally an XL, I ordered XXL and fit perfect.

Good jacket for the price
Size: Small, Color: Gold, Size: Small, Color: Gold
My son had prom and the theme was, "Your Night to Shine," so he and his girlfriend decided they needed to SHINE. And when this boy picks for a theme, he picks! He is 5'11 150 lbs, very thin, but also muscular and ordered a small. The sleeves were a bit short on him, but that's to no fault of the jacket, it's just been his life as a tall, lanky kid. Great quality, steamed the creases out easily, and stayed together the entire evening. Excellent buy!

Great for the stage. A bit iffy up close.
Size: Medium, Color: Silver-3
Jacket is decent. It’s good for the stage. It looks a bit cheap up close. Probably good for prom but for an adult wearing it to a function I can’t say I would recommend it. But it’s great for the stage! We have worn them many times and they hold up well. I’ve even washed them in the washing machine on delicate cycle without any problems. Just hang it to dry and you’re good to go. It holds it shape and doesn’t wrinkle. A good value for the money. The sequences are this color as they are shown. The sizes are true to fit.
