If you're looking for a place to buy a Carnival or Halloween costume this is the right one…read more However, be prepared to spend some €€ because it's not cheap to dress up. They have tons of costumes, wigs and accessories for every costume: vampire fangs (don't go for the cheapest, they are super bad quality), fake blood, make up, gloves, fake scars, etc.
What I liked about the place, besides the variety of stuff, is that they also sell party supplies like themed plates, glasses, tablecloths, etc. Also, staff is nice and helpful. You can buy on their website but if you want to take a better look to the costumes and accessories it's better to visit the shop.
What I didn't like are the prices (but it should be expected also in other places, at least most of their products are made in Italy) and that the place is tiny, and you can't get a nice view of the costumes since everything is a bit messy and when there's more than 5 people in the shop it feels crowded. Try not to go on lunch break the days before Halloween or be prepared to wait a bit to be helped or get a good look at everything...
