Personally I'm super happy that I brought lab coats from back home. Most of the ones here are made out of this super thin, semi-see through material and anytime there's even a slight breeze you see them flapping about everywhere. If you're planning on going to the trouble of coming here and then buying a special material(that's thicker) and then getting some tailor made you might as well just buy them from home. Definitely much easier. Tailor made or not, the ones from back home will probably fit better too.

If you don't have enough time to order them online you can just go to a local med school bookstore and buy some from there. That's what I did. I bought 3 and haven't had any issues of not having a clean one, but it'll depend on your laundry situation. It's not as convenient as ordering them online (especially if you want embroidery) but great for those of us who remember to buy lab coats at the last minute.
