There's always vintage & antique fairs on in Dublin, run by Vintage Ireland, and I've been to numerous ones in different venues. There's always so much to chose from- from retro clothing to antique furniture. Not only that, but it's a brilliant day out, with fashion shows, live music and lots of vintage fun! There's one taking place tomorrow in the Celbridge Manor Hotel, and admission is only €3.50. If you're around I'd highly recommend popping in, as I'm going myself and can't wait! I wrote about one of the fairs here if you want to read up on what goes on.
5. Temple Bar District
Last but not least is the Temple Bar area in Dublin's city centre. There are so many vintage shops to chose from! Three of my favorites are Fresh, Eager Beaver & Lucy's Lounge. As you can see from the photos above, even the outside of the shops are quirky! They're all pretty near each other too, so you could easily hit them all in one day. Eager Beaver sells a lot of vintage inspired items, Fresh is very 90's grunge and Lucy's Lounge also stocks some handmade pieces.
So there's my guide to vintage shopping in Dublin! Let me know if you check any of them out, or if you have any recommendations for me.
