Much better quality than I expected

Better than I expected, actually a quality jacket. I'd wear it every day. The fit is perfect and exactly my style. I can't say much about washabiity due to having mine drycleaned

I received so many compliments on this jacket! 5’6” 140lbs. Fit like a glove but a little long. I will get the sleeves shortened.

Ruined prom for my senior
Size: 3X-Large, Color: Bright Purple
• The seller's failure to cancel an order, despite promising to do so, resulted in the buyer ordering a replacement item and incurring extra costs. • Poor communication and unhelpful customer service from Amazon led to significant frustration and disappointment, impacting multiple important events. • The buyer will no longer use Amazon. Awful material EXTREMELY WRINKLED ill fitting. SAVE YOUR MONEY AND YOUR SANITY!!! DONT RECOMMENDED EVER!!!!
