You're not alone in this mistake. I needed a first suit for a job interview and went to MW as well. Bought their "best" quality suit and left it with them for alterations. Right afterward my wife dragged me to Nordstrom's to look at women's stuff. Wandering around bored, I stumbled into the men's suit area and totally by chance slipped on a Canali. Oooh damn! Exactly like the day I drove my Civic to the BMW dealer and took a test drive. I immediately took out the MW claim stub to get their phone number, called on my cell and cancelled the sale/alterations. Luckily they did not have time to start the alterations. Wearing the Canali, I absolutely strutted into the interview just knowing I looked as good as was possible (got the job). Now my only regret is that I paid full retail for the Canali. Never drive your BMW to another dealer and take a test drive. If yours is like mine, it will take offense and attempt suicide by catastrophic water pump failure.
