Buying a bra is not always as straight forward a process as we would like it to be. Different brands are cut differently, some materials stretch more than others, certain styles are more flattering than others, etc. However, there are some easy guidelines that you can follow to make buying a bra an easy an enjoyable process.
Firstly, calculate your bra size. Although I have heard people use a variety of complicated formulas to make this calculation, to me the simplest way to calculate your bra size is by using a calculator such as the International Bra Size Calculator
Now that you know your bra size, you should try out different style bras to determine which is most flattering to you: strapless, full cup, racer back, push up, etc. Always take into account that if your breasts are a little on the small side, some extra padding might be preferable while if your breasts are very large, you might prefer a support bra. Also take into account your daily activities. For instance, if you exercise a lot or engage in various physical activities during your day, you might prefer a style that is comfortable and stays in place. On the other hand, if you wear a bra for a special occasion, you might then choose one that enhances what you are wearing and some bras are even meant to show under your clothes since they are beautifully made to enhance your fashion.
Lastly, do not stick to any particular brand or designer until you find the perfect fit and style that suits your taste and lifestyle. But once you do, go shopping and start building a great bra collection for every occasion. And remember, have fun doing it! Bras are a synonym of femininity and say a lot about the person wearing them.
