Fashion the fun (& sometimes, FREE) way
Check out Castleknock Freecycle (for free stuff including summer clothing).
Or browse the local charity shops for great second hand value. There are superb second hand clothing shops in our area, with three situated very close together in Blanchardstown Village. You could also check out the NCBI store in Dunboyne, if you are passing that way. It's has a great store layout and the staff do very impressive editing of their outfits! Why not hunt for a bargain this summer? It's great fun and you might bag a vintage find.
