The fitting rooms are very small, and since this is a secondhand shop you have to look the garments over very carefully to make sure it's in good enough condition to buy, and you can never be too sure what they have ready to buy.
That said, I got my wedding dress for $100 and it is beautiful! It probably cost the original owner around $800 or more, it was an absolute bargain! There were a couple minor stains, but Grandview cleaners (right down the road from the alternative resale shop) was able to remove all the stains, clean and press for under $50.
I am a very satisfied customer! I think it is worth a look, just to see if they have anything you might fall in love with (like I did)
