Maybe I went on an off day but this market was AWFUL. As you enter, there's a mix of horrible cheap…read moreflea market clothes and used clothes..but you have to do a lot of digging in the used clothes and I didn't find anything that needed to come home with me. As you walk further in, there are vendors with used merchandise but anything even slightly antique is jacked up in price as soon as you show any interest in it. At one booth, I had collected a small pile of stuff and the vendor wanted 40 euros which was outrageous. I asked him if he would take 25 & he said "D'accord"..so I pulled out the 25 and he just looked at me like I was handing him a turd and stated the price was 40. Guess I should have just put all the stuff down and walked away but I had spent time picking the crap out and didn't feel like putting it back. So I paid 40 euros for a vintage 60s pink leopard top, small section of black maribou feather boa, broken watch, a few rhinestone pins and a 60s vintage hat that wasn't that great. Live and learn. All in all this market was really grubby and grimy and if you are at all a fan of the beautiful and magical parts of Paris, you will NOT like this place. At all.

I found a super fun hat that was also affordable (25 Euros for an awesomely colorful hat--see photo), and the shop keeper helped me with how it should be worn. They had numerous styles: newsboy, cloche, small brimmed, with flowers, with bows, with feathers, with bands. Felt, canvas, velvet in lots of black, grey, red, navy and brown. Chic and affordable.

The owner is super helpful with finding sizes and colors. He even found a hat in a big enough size for my husband. The red hat I got for 30€ was exactly what I was looking for. I'll definitely come back for another one the next time I'm in Paris. Lots of hats/colors/sizes for reasonable prices.
