The short answer is yes, you will need a partner. Can you find one in the class? Yes, you usually can. But, let me just say something about learning tango with someone you don’t know compared to someone you know (even a little), compared to someone you know feel and comfortable with. There’s a big difference. So yes, you need a partner, but try and find someone you know to do this with and if you can’t it’s ok, you’re just going to need to build a rapport with them first. If you’re still worried, drop me an email.
Whatever you like as long as it is comfortable and easy to move in. Remember the sessions are for learning so save the LBD for the milonga. Expect to get warm so make sure that you smell good (not overpowering) beforehand and are able to stay that way (spare shirt?).
Shoes should be thin soled and not sticky, you will need to pivot (turn) in your shoes. A strap holding your foot in your shoe is important (no flip flops or slip ons)and a lower heel is advised for ladies who are starting out.
It is not possible to reserve places. Your places are only confirmed when you receive a confirmation of payment email.
