How much
....with Lord and Taylor I've always been able to talk them into doing it for free.
With Jos A Bank, I forgot, I had their tailor do a Trench Coat and a suit for me. The Korean tailor was cheap (Korean prices), they did a RL suit for me, something along 25-30 dollars, for two days (they could have it in 1 day)...
they are kind of pricy
You are in med school, you'll be able to afford it, if anything, they are lower mid to mid level, Brooks Brothers near me is good, but their tie selections aren't as good as Jos. A Bank---that is my "thing", ties...if a place doesn't have good tie selection, it shows that they only really care about selling a product...not selling and complimenting the product to it's fullest.
