All of the dresses and accessories are donated by brides and proceeds go to cancer research. I just love this concept! Prices are great, everything is under $1000 with most dresses well under. I came here twice, first to find a dress and second for accessories. Both times I didn't have any luck but I was very happy with the experience.
They have a great online appointment booking system. When I arrived, I was met with friendly volunteers who quickly explained what to expect. There are a few different rooms with dresses. One rack had used 'higher end' dresses in garment bags. I was looking forward to this rack the most, but the selection was small (~30 dresses)
They said to factor in ~ $300 for dry cleaning. The also have some preferred seamstresses for alterations, I ended up going with the seamstress they recommended (Pearl Seto who was great!).
I was happy to try on dresses that were already altered for my height (unlike the bridal shops which are always too long), this gave me a more realistic idea of what different styles looked like on me. It was an eye opener.
