Decide what type of boning you require in your corset, Plastic boning is the cheapest and most common type of boning found in modern corsets. If you're after a pretty top or something to impress in the bedroom, then go for this option.
Steel boning comes in two different types, spiral steel and flat steel. Spiral steel is more flexible than flat steel, and they are often both used in the same corset. This type of boning provides a lot more support than plastic boning and is usually much more comfortable.
Decide whether you want an overbust or underbust corset. An overbust corset covers the breasts, while an underbust corset stops just below them. Underbust corsets are far easier to buy off the rack than overbust corsets as they go by the waist measurement only, rather than waist and bust.
Take your measurements with a tape measure.If you are buying your corset off the rack you will need to know
your waist measurement and, if you are buying an overbust corset, the
measurement around your bust. If you are ordering a custom corset online they will tell you what
measurements they need. This will probably include the measurements
around your bust, just below your bust, your waist and your hips. They
will also need to know the vertical distance between each of these
measurements in order to give you the best fit possible.

Try your corset on, there are a few things you will need to consider when you try on your corset to make sure that it is suitable.
Ask about how you should clean your corset. You can't
normally chuck a corset in the washing machine with everything else.
Most corsets need to be dry cleaned or hand washed, and they should be
cleaned only rarely. Where possible, wear something between the corset
and your skin to reduce the frequency of washes. Make sure you will be
able to clean your corset before you buy it.
