Buying Guide
Blue Designer Knitwear Edit
The best blue designer knitwear worth buying covers more ground than most people expect, from icy powder shades to deep navy and electric cobalt. We pulled together 36 pieces across the houses we trust for knit: Burberry, Mulberry, Maje, Sandro, Acne Studios and more. Blue is the colour that slots between a neutral and a statement, so it wears like a wardrobe staple but reads more considered than grey. Here is what we would actually reach for, and how to pick the right one.
Blue jumpers
A proper run of blue jumpers, and this is where most people should start. Expect crew necks and roll necks from Maje and Sandro in merino and wool blends around the £150 to £280 mark, with Acne Studios bringing the boxier, slightly oversized cuts. Navy is the safe buy that goes with everything you own. If you want one piece to earn its keep, a mid-weight navy crew is it. Cobalt and powder blue are the ones to add once the basics are covered.
Blue cardigans
Blue cardigans do the work a jumper cannot, layering over shirts and slipping off when a room overheats. We rate the fine-gauge button-throughs from Maje and Sandro for desk-to-dinner wear, plus the chunkier shawl-collar and grandad styles you will find from Acne Studios. Navy and denim-blue are the versatile picks. Check the buttons sit flat and the ribbing has spring to it. A good cardigan holds shape after a wash, so the yarn quality matters more here than on a jumper.
More blue knitwear to discover
The widest part of the edit, and the place to browse when you already own the obvious navy crew. This pulls in vests, zip-throughs, polo knits and the odd statement piece in cornflower, teal and inky midnight from across Burberry, Mulberry, Maje, Sandro and Acne Studios. Prices stretch from accessible merino up to cashmere worth saving for. Use it to fill gaps: a tank to layer, a brighter blue to lift winter greys, or a heavier knit for actual cold. Buy on shade and weight, not just the name.
The buyer's brief
How to choose
Blue knit lives or dies on the shade and the yarn, so a few quick checks save you from a piece that pills by February. Use these to narrow the selection.
Pick the right blue for your wardrobe
Navy behaves like a neutral and pairs with black, grey, camel and white, so buy it first. Cobalt, cornflower and teal are the pieces that lift an outfit, but treat them as your second or third blue, not your only one.
Read the yarn before the brand
Merino and lambswool give you everyday durability, while cashmere and cashmere blends feel softer but pill faster and cost more. For a piece you will wear weekly, a tight-knit merino is the sensible call.
Match the weight to how you will wear it
Fine-gauge knits layer under jackets and over shirts without bulk. Chunky cable and shawl-collar styles are warmer but read as outerwear, so do not buy heavy if you mainly want a layering piece.
Check the shape holds
Look for firm ribbing at the cuffs and hem and buttons that sit flat on a cardigan. Knit that has spring to it keeps its shape after washing, where a slack, loose-gauge piece tends to drop and bag at the elbows.
Size for the cut, not the label
Acne Studios and similar houses cut their knit boxy and oversized on purpose, so size down if you want a closer fit. Maje and Sandro run more fitted, so take your usual size or go up one for a relaxed look.
Decide between a hero piece and a workhorse
If you want one knit to last years, spend on quality navy in good yarn. If you are after a colour hit for the season, a brighter blue at a lower price does the job without the commitment.
Good to know
Answered
Navy goes with almost anything: black, grey, white, camel and denim all work. Brighter blues like cobalt sit best against neutrals, so pair them with grey trousers, white shirts or beige rather than competing colours.
