where can i buy a size 36a bra?

There are several different places for you to purchase a good quality bra in a size 36A.  Victoria Secret has the best bras ever.  They have several different bra lines so you will always find the perfect bra just for you.  I usually will wait for them to have a sale ( which is at least every 3 months or so) and try one of these bras for yourself at a very reasonable price.
You can also try J C Penney .  They also have a nice and comfortable line of bras.  I have some family that purchases these and they love them.  They say that the style and fit is fantanstic.

There are lots of beautiful bras out there...it really just depends on what you want! From sexy to every day, your options are limitless...There are the higher end stores like http://www.victoriassecret.com to the bargain friendly prices at places like target or sears.
