Bad Attitude is a fun little shop. It was a lot like a Halloween Adventure and a Frederick's of Hollywood had a baby. What the previous Yelpers have said is true: they offer top-quality merchandise and charge accordingly.
They have a downright shocking number of corsets! If that's what you're buying, don't go anywhere else. A HUGE array of colors, sizes, and styles are in stock and you can even check out swatches to have others custom-made.
Outside the corsets, though, the extended size choices here are limited. The salesclerk was welcoming and knowledgeable and I would totally send my friends here in a heartbeat.
