crewneck sweaters

[JugglingAct123]

I really love the J Crew 'Tippi' style sweaters but they are slightly too short on me (I am 5ft 10)
Does anyone know another company that specialise in really high quality and chic looking round neck sweaters in classic colours?

John Lewis or Pure Cashmere. There are always offers on at Pure if you sign up. I also wear M&S autograph cashmere crew necks a lot as I find them quite long in the body. Uniqlo cashmere is also well-regarded on here but I haven't bought one
Brora is amazing but spendy. I would always opt for cashmere over merino. You do need a cashmere comb and there is some inevitable bobbling at first but this is easily sorted.
I think you do need to try a few on though, sizing up or down to see what suits you best.

Uniqlo merino wool

I have a uniqlo merino crew and a different cashmere one and I have to admit unless sizing up they tend towards the short side on me and I'm 5.4. I've seen colourful crew sweaters in John Lewis (I think these were longer) and massimo dutti and all of dame's recommendations look good.
