Walmart has a lot of options thats where I got most of his clothes. Also carters online they have tons. Amazon has e few as well I ordered his fleece sleep and play onesies. Hope that helps x
Asda and Matalan have great tiny baby ranges that I bought for my baby (she was born at 29 weeks)
Next have a great range of up to 5lbs. X
Next and M&S. My daughter was 3lbs and they were the only places that went small enough. I found Matalan and Asda were good for around 5/6lbs

Asda was my go to when I had my LO x
John Lewis, asda, matalan I used mainly from them xx
I got one from target.
M&S have really small sizes
Next do a good range, under 4lb and under 6lb stuff x
My daughter was 4lbs and I got her preemie clothes from Carters (tons of very adorable options) & Walmart. Target didn’t have a lot of preemie options.
