Open weekends at Cockpit Studios are a good chance to catch up on makers working there as well as meeting new ones.
Prudence Millinery produces outsized hats (recognise them from Vivienne Westwood in the 1990’s?) and has been based at Cockpit in Holborn for several years but I’d never stopped for a chat and try on before. She was preparing a shipment to one of her key markets, Japan, hence the piles of straw bowlers below. 
As ever though, my favourites were by far the most expensive ones shown below, the bases hand stitched and formed by Prudence for her Prudence Couture collection
I don’t often lust after things but I do love those hats.
Hi Caroline, is Prudence still making oversized hats? as her website is down and there is very little I can find on her now.
Hi David, I don’t know if she’s still at Cockpit Studios but her Instagram is still active @prudencemillinery1 so maybe DM her there. Good luck!
