We want to make your shopping experience as convenient and pleasing as possible. If you have any concerns or need some further help please email us at and you can be assured to receive a reply.

To help you get started, here is a list of the most frequently asked questions that may provide you with an immediate answer.

Is paying online safe?
Yes it is, probably more secure than writing a cheque, giving your card number over the phone.

Who does BETTY DIAMOND use for payments and why?
We use the PayPal payment system.
The advantage to you is that we never actually get to see your card details, only your delivery address.
PayPal does all the processing for us and charges us a small fee.

How can I pay if I don’t want to use PayPal?
You have the option of simply entering your card details and postal address for delivery. It still goes through the secure PayPal payment system. It’s that simple. Alternatively if you’d like to make a direct deposit please email and we’ll give you our details.

How long will it take for my order to arrive?
As long as your chosen garment is in stock, if posting in Australia, about 1-4 working days, overseas dependant on which country you are in so please email and we’ll be able to give you an estimated time.

What happens if I want to exchange an item/s purchased?
As long as the item/s is in original condition, simply email us on with your invoice number or PayPal receipt no. and your requirements first, and then send the original item/s back to us by post within 14 DAYS OF RECEIPT OF DELIVERY to:

3/8 Dundas Street
Coogee NSW 2034

Always be sure to give your name, phone number and payment details along with your address and invoice number.
We will cover the cost of shipping out to you the first exchange, however subsequent exchanges will incur additional postage charges (please see our return and exchange policy). You will be charged for any additional items sent if you fail to return the original items back to us by the specified time period.
Please be aware that we can only exchange items if stock is available.

What is your refund procedure?
Returns will be processed within 3-5 business days of receipt at our warehouse. We will only refund payments onto the original card used. You will be then sent a confirmation email. Please note that when we have refunded your card your account will be credited according to your bank’s processing times.

I have changed my mind – can I swap or get a refund?
Yes you can, but the postage costs are your responsibility and the goods must be unused and must be returned to us within 14 DAYS OF RECEIPT OF THE SHIPMENT.

How heavy is the fabric of the BETTY DIAMOND swimsuit? Will it dry quickly?
The fabric is heavier than lycra, it’s firm and it has some water repellency so it dries quite fast. Remember to rinse after every wear.

I am really unsure of which size to choose, what should I do?

  • Usual bra size
  • Waist
  • Hip
  • Torso length (see illustration on swimsuit page)

seems to be the average…
