Anyone know of any similar companies to these two, really nice acetate frames in some nice colours.

I especially like the first links prices, unfortunately they are US only and the second brand are a bit pricey.

Alternatively, you could track something you like down on eBay and get them reglazed by someone local who does good optics.
That’s what I did.

Take the pic to a GOOD indipendant opticians, they will have lots of catalogues where they should be able to find something very similar, most would be able to get the frame in on approval for you to look at b4 buying too

Specsavers have some great acetates at the moment. Full range on line.
Not just the designer ones either. Take a look.
