Oh I love a baby clothes hunt!
Wow... it's harder for boys. There is so much more "traditional" stuff out there for girls. Anyway I have found some things so hopefully some of this will be helpful

Mothercare other:
Farm themed vests - a few bright, but stripy, some with little chicks on
Gorgeous yellow and white set of vests
Matching sleepsuits
I love these soft coloured giraffe ones, but long-sleeved might be a bit hot now. Could use as nightwear in a growbag though.
Yellow and white set with tiny bear motif on
Cute summery white hat and romper set
Humphrey's Corner again in blue0 - they also have a few bibshorts (the dungarees which don't have legs like this, for summer) in H&M in the baby section.
