Fashion icon Elle Macpherson knows a thing or two about lingerie - she used to be the 'it girl' for Bendon.
However she is now taking on the very company she used to work for with her own line of lingerie.
Ms Macpherson has touched town in New Zealand, ahead of the launch of her brand Elle Macpherson Body at the Queens St Farmers store on Thursday morning.
However before you race to buy the latest underwear trends, there are a few things you might want to consider.
Newshub spoke to bra fitting expert Michelle Saint from Avokado Lingerie about the most common misconceptions when it comes to buying a bra.
Ms Saint says this is the most commonly made bra shopping mistake. She says many people don't realise the volume of cup changes with the band width.
"The cup volume changes with the band size, so put quite simply an 8D is a different cup volume 12D. Some people might say 'I'm a D cup' but to us bra fitters saying you're a D cup doesn't actually mean anything to us without the number in front."
The two cup sizes Ms Saint mentioned are indeed 4 cup sizes different. In fact the volume of a 14DD cup is the same as a 12E, 10F or 8FF bra.
"The general rule for bra fitting is when you go down in a band you need to take it up in the cup," she says.
The bra fitter says many people tend to wear the band looser than they should. She says this could stem from not wanting 'back fat', or for comfort.
"A lot of people will feel that the support of their bra needs to come from the straps and tightening their bra straps up but the majority of the support from the bra should come from your back band."
Ms Saint says in theory you should be able to drop your shoulder straps from your bra and have it stay in place.
A good tip is to buy a bra that is comfortable on the first eye hooks when brand new, this allows women to tighten the band as the bra naturally stretches.
Ms Saint says if an underwire bra is fitted correctly, it should be as comfortable as any other.
"If your bra is digging in and you can't wait to take it off at the end of the day, it's highly likely you are wearing the wrong size."
"I think poor bras get a lot of bad press because people can't wait to get them off but it's only because they're just not the right size."
Ms Saint says women should try on every bra before they buy it because there can be discrepancies in sizing and she says it always pays to be professionally fitted.
