One thing I can't stress enough, is buying a good bra. It may not be cheap, but it will help give you shape, and hold everything together. Buying a bra should be an investment, not a cheap fix. A good bra will cost you about $50, and trust me it'll be worth it once summer hits and you want to wear all those low cut dresses. Without a good bra, you'll look unshapely and make even the best clothing look unfitted. I recommend Dream Angels Push Up by Victoria's Secret. Although they have many beautiful colors, it's best to buy a nude one because you can wear it with absolutely anything and it won't show through. This is a bra every single woman can (and should) wear.
