Generally, you should order your pre-pregnancy size (in other words, the size you wore before you were pregnant). Our sizing takes into account weight gain and a growing belly all the way to 9 months. When selecting your size, use the measurements chart below as a guide.
|Mermaid Maternity® Size||Small||Medium||Large||XL||XXL||2X|
|Current Bust Measurement* (inches)||36-37.5||38-40||40.5-42.5||43-45||46-48||47-49|
|Current Hip Measurement** (inches)||38-39.5||40-42||42.5-44.5||45-47||48-50||49-51|
For larger bust sizes: If your bra cup size is DDD or higher, you may want to go up 1 size, but we do not recommend going up 2 sizes. For example, if you normally wear a size medium in a fitted t-shirt but your bust measurement falls within the 'Large' box in our size chart, you should order a size large. However, if you wear a size medium in a fitted t-shirt but your bust measurement falls within the 'XL' box in our size chart, we recommend ordering a size large, not an XL.
If you have specific fit questions feel free to contact us. When you try on your swimwear, keep in mind that it will stretch a bit when wet.
