I've been to this store several times now and have always received good service. They carry a wide range of sizes and have both a good selection of basics and fashion bras.
Occasionally the quality of the bras can be hit or miss. Change sometimes uses scratchy laces and threads, so it is really important that you run your fingers over every part of the bra to make sure it is smooth and soft. I have bought a few bras without doing this and ended up only wearing them once or twice before I got rid of them - but the bras I have checked over carefully in store have ended up being the bras I wear the most.
Be careful when shopping here (take your time!) and you will end up with properly fitting bras that you love.
