Hey Sarah,
BHS had some great stuff summer baby/toddler stuff yesterday.
Boots - Emmylou mentioned they had their summer clothes at £1 for an outfit - but they didn't in my local one- maybe you'll be luckier?
Baby Gap - my local one had lots of summer things, but still fairly expensive in my opinion, similarly with Mothercare (but I think their sale is finished) - however these are both like £10.50 for an outfit, rather than £20, which is out of my budget - I like charity shops - oooh there's an idea for you?!?
Hope you are lucky!
