Every first Saturday of the month the Dalston bar "Birthdays" hosts a "vintage sale". Its not really a vintage sale, its where individuals choose to sell their old clothes at a really really cheap price. I found a Zara top I wanted from 2 years ago there for 5 pounds. They have some designers stuff, some high street clothes, and some quirky individual make clothes.
You walk into the bar and you can order coffee or food, and browse through the racks of clothing and accessories. Some people were selling clothes that were really summery and weather appropriate whereas others were selling clothes for all types of different weather. On the ground floor there are loads of different sellers lined up around the "edge" of the room. You then go down a set of stairs where the bar's dance floor usually is and there were more racks of clothes. The colours of the clothes were harder to see downstairs because the lights aren't very bright but there were more unique clothes in the downstairs section.
Sadly, I didn't find anything, but hopefully I'll be going back on the 1st of June to see if they have anything better. I also want to go there at night cause my friend Daniella said that there was a really good vibe there the last time she went. Also, I really like the venue's logo, its so cute, I love that font!
I heard of this event through Facebook, but you can also find it on the Birthdays website: http://birthdaysdalston.com/
