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!!!!
