Beach Belle & Caribbean Delight came with clothes: the dress you have, a hat, & a wrap skirt. They are very HTF & go for over 100. I saw a complete set go for £300. I'd guess maybe £200-250 for yours, dependent on condition (I think similar in US dollars & euros too)
No clue on Italian Bubbles as not keeping such a keen eye on her as I am on the G3s. I'm holding out for a complete set with them (all clothes in it)
