There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars). The story of that auction is well-known so I'll only...

But if you really want some tips, simple is really the way to go. A solid colour t-shirt, blue/black/tan chinos or jeans, a bomber jacket and white or black sneakers is a cheap, stylish look that a 16 year old can wear anywhere.
The best advice I can give you is to find your own style, you will make mistakes along the way but that's how you learn. Try to avoid statement pieces if you don't know your own style however - avoid leather jackets, unique hats, vests, blazers, all "classy" wear etc. All of these things can certainly work, but only if the wearer knows how to pull it off, and that the style works for them. You'll learn eventually what unique items you can wear and what to wear them with.
You can get decent, cheap clothes from stores like H&M and Uniqlo. Once you work out your style after wearing different cheap clothes over the years, you can start to shell out the cash for quality key pieces of clothing (shoes/boots/outerwear/jeans). Here's a couple of basic guides to a standard fashionable wardrobe.

The last thing is fit - probably the most important part. If you're used to your parents buying clothes for you then you're probably used to wearing clothes that are too large. Generally speaking, you want all of fabric of a shirt to be touching you (but not tight). Pants shouldn't be baggy around the bum/crotch or waist (the legs differ according to the style).
Good luck.
