* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.

While I would give the bra 5 stars because it's awesome, I won't because it was an exchange and customer service told me I couldn't use a credit/gift card to pay for the difference. What a silly rule. Credit/gift cards can't be used for exchanges? Who cares where the money comes from? Great bra! Buy one.

I have several of the Sieve wireless bras and thought I was ordering more. But discovered the item I just bought has a clasp in back. Not what I wanted at all! I can only use a pull on style so I will have to search for other brands that meet my needs.
