We've also developed some relationships with boutique owners in other countries and we often split orders or send each other "one off" items. The reason for this is, we're not able to comply with some companies minimums and then pay the shipping from Europe or Australia. It would not be cost effective for us or for you. Again, that's why you may see only one item in one size.
We shop this way to bring you hip, new designs, while keeping the cost well below retail.
