Can you post pics? If you'd post some of you in your favorite tops we could give you some ideas to go along with it.
It's essential that you figure out your lifestyle and then you'll shop more effectively. I hate wasting money too, so this was a great revelation for me as well!
So, you are a college student, so you go to class, and you probably work. What kind of clothing do you need for this? Do you walk alot? (High heels would then probably be low on your list, more for going out on a special night, so you might only need one really great pair!)
Do you have a little black dress? I just bought my real first one (and I'm 48) and I can't believe how versatile it is! It's sleeveless and a heavy knit for the fall, so very comfy. I can wear it with a jean jacket an black tights boots (of almost any height, ankle, calf or knee high) for a casual vibe. Hose and strappy shoes with a pashmina for a more upscale look or even with leggings and boots! I can wear a shirt over the top with a belt so the bottom looks more like a black skirt, and I can wear it with a blazer or a leather coat...Cardigan or a scarf would be another look for this dress.
What kind of vibe to you want to present to the world? I prefer a very casual vibe so that's mostly what I shop for. That means jeans as my bottom most of the time, (skinnies, bootcut and flare, along with boyfriend and white jeans) are in my closet, and a couple of pairs of black leggings (ankle length and knee length)
I'm trying to stick to a color palette that's versatile and works for me, so black white and red are my first choices, and then I add in other colors as the mood strikes me. (Black and white are really my base though).
There's lots to think about but if you consider your lifestyle and ask yourself "What will I wear this wiith? (Including your footwear and purse) and if it works with a couple of outfits I'd say you'll probably get lots of wear out of it.
And if not you can sell it on Ebay! LOL
