I'm going to the Andre Rieu کنسرٹ at the metro radio arena and would like to know what the dress code will be?

That is really great! I think the dress code depends on location, location, location! Also the price of the tickets also gives a little clue too. But, anyways, I believe that for something really formal آپ will want to if your a man invest in renting a tux یا a really nice suit. If your a woman a long dress should do. آپ can pick the color if آپ want but classy colors like red, black, etc. are the best. If it is not as formal for boys just wear a nice button up شرٹ, قمیض with some nice pants. If your a girl آپ could pick the same color dress and\or style but a little shorter. Well i hope آپ have fun at your concert!!
