I've put together a whole page of items perfect for spring and summer, which are all available from Pin-Up Parade.
If you're feeling particularly summery, of course, there's always a tiki dress. This dress is in stock in all sizes from a 34" to a 52" bust, by Nicole Katherine. You'll find it on the Dress page.
