That's a really good price, at least for the places near me. I think trying it for 4 weeks is a great way to start so you aren't stuck if you don't like it. I would say go in with an open mind and listen to what they tell you. Also, if you get confused by a pattern or technique, don't be afraid to ask questions. Learning proper technique can be frustrating but its worth it, also try not to be too self-conscious. You may feel like something looks stupid but I promise it looks better than it feels, especially arm movements. As far as clothes go, I personally dance in jeans (I'm a hick at heart and don't own much of anything else) but I get complained at a lot. Leggings/sweat pants or really anything you can stretch in is good for starting- the main problem with jeans is that I can't do splits and things like that in them but they shouldn't be too picky if you're just starting. Also bring a hair tie. Back to dancing- try your best to follow instead of anticipating what your partner is doing and trust the person you are dancing with. Most importantly, just have fun and enjoy it- it isn't even worth doing if you don't find it enjoyable. You'll like it, it really is fun and can be good excise.
