Once you have bought a bra here, you will never go anywhere else! I have yet to find more experienced bra fitters. "Fitters" at the chains (ex. Victoria's Secret) claim to be trained at bra fitting, but don't be fooled. You will get the BEST fit at Petticoat Fair. You will feel so much better in your clothes and look so much better too. What a difference a good fitting bra makes!
They carry all sizes and types of bras and are bra fitting experts.
This is also an excellent store for nursing bras--and it can be especially hard to find a supportive nursing bra. They have plenty to choose from here.
