It's more common than you think - pregnant bridesmaids, that is! Just because you’re getting married doesn’t mean everyone else's life stops. One of your girls may already be pregnant or find out that she is pregnant during your engagement. Learn the answers to questions many pregnant bridesmaids ask, like how to order a bridesmaid dress when pregnant or post-pregnancy, the best styles, and how alterations work.

Maternity Bridesmaid Dress Advice for Pregnant Bridesmaids

Let’s start with the basics: ordering a bridesmaid dress when pregnant. The size you order will be determined by how far along you will be at the wedding. Here is a timeline for general recommendations when it comes to maternity dress sizing.

Maternity Bridesmaid Dresses

  • 3-4 Months: If you'll be pregnant AT the wedding, plan to order your bridesmaid dress one size up based on your current measurements.
  • 5-6 Months: For bridesmaids who will be 5-6 months along AT the wedding, you should order your bridesmaid dress two sizes larger than your current measurements.
  • 7-9 Months: If you'll be 7-9 months pregnant AT the wedding, order two sizes up and consider purchasing extra fabric for alterations.  With a large bump, your bridesmaid dress may lose too much length in the front. So, providing extra matching fabric to your seamstress will be extremely helpful!

If this is your first pregnancy, or first time as a pregnant bridesmaid, dress sizing can be confusing. When it comes to sizing for maternity bridesmaid dresses, we have some advice to make the process easier!

How to Take Measurements for Maternity Bridesmaid Dresses

Measure and note the fullest part of the bust. If you're ordering a maternity bridesmaid dress, waist measurements can be taken, but are not needed! This is because maternity bridesmaid dresses are made to house a baby bump.  Check out our maternity bridesmaid dress size chart below to find your best fit.

If you choose to order a standard size bridesmaid dress when pregnant, sizing will be different! It is likely that alterations will be needed at the waist, as standard sizes don't account for a bump. However, bridesmaid dresses with fuller skirts will help ease this issue. If necessary, visit a professional seamstress or dress shop for help with taking your measurements.

Do I have to Order A Maternity Bridesmaid Dress If I’m Pregnant?

This simple answer is NO. However, if you will be 5 or more months pregnant at the time of the wedding, we recommend that you buy a maternity bridesmaid dressIn the case that you do order a standard size dress, alterations will be needed to achieve the right fit. Standard bridesmaid dress sizes are designed around typical measurements. So the material will not account for a baby bump. It may grab and pull, and even alter the appearance of the dress when worn.

When considering styles, look for bridesmaid dresses that have an empire waist with a full gathered skirt. This style features a waistline that will sit comfortably above and drape your baby bump. If you choose a more fitted bridesmaid dress through the waist and hips, you’ll likely need to size up.

Ordering a Bridesmaid Dress While Trying to Get Pregnant

So, you’re thinking you MIGHT be pregnant by the wedding rolls around, but aren’t 100% sure that will be the case. What should you do?  

If you are not pregnant at the time of purchasing your bridesmaid dress, but are trying to become pregnant, we recommend ordering 1 size up.  In the case that you do become pregnant, there will be enough room to grow into your dress come time for the wedding. Note, this depends on when you order your dress and plan on becoming pregnant. Do your best to estimate how far along you will be come the day of the wedding.

Dress Measurements

In the case that you’re not pregnant by the time of the wedding, your dress can be easily taken into your original size. Remember, it’s easier to alter your dress down a size than it is to make it bigger!

How to Order a Bridesmaid Dress Post Pregnancy

First of all, CONGRATS! We hope you’re enjoying every moment with your bundle of joy. Before, during, and post-pregnancy, you deserve to feel beautiful. Whether you feel more confident wearing a maternity bridesmaid dress or standard dress is completely up to you!  That being said, it’s recommended that you order your bridesmaid dress 1 size up post-baby. This will allow a little more room for your to remain comfortable as your tummy begins to shrink in size.

Important Things to Consider for Post-Pregnancy Dresses:

Breastfeeding: If you’re breastfeeding, make sure to allow for extra room in the bust area! Try to choose a bridesmaid dress that is comfortable, supports your bust well, and allows easy access in case you may need to feed or pump. Don’t make the task any more difficult for yourself!

Weight Gain: Here’s a gentle reminder that you probably won’t match your pre-pregnancy measurements immediately after giving birth. Take it easy on yourself - you’ve just birthed a human after all! And now you’re generous enough to support your girl on her wedding day, baby in tow.

How to Alter a Bridesmaid Dress for Pregnancy

So, what do you do when you’ve already ordered your bridesmaid dress - BEFORE you knew you were pregnant?

Depending on the bridesmaid dress style and how far along you will be, will determine what can be done. A fuller skirt is easier to alter, but extra fabric may be needed. Allow up to 2 to 4 months for fabric.

Even if you think you’ve ordered the correct size, your body still may change in unexpected ways. Baby bumps are unique to every person! To make sure your bridesmaid dress will fit, plan to have alterations done 2 weeks before the wedding. Just make sure to contact your seamstress well in advance.

Additional Tips for Pregnant Bridesmaids

For starters, opt for maternity bridesmaid dresses when possible! Maternity bridesmaid dresses were created for a reason. They'll save you money on alterations, provide greater comfort, AND to better flatter your new body. Sounds ideal right?
Second, consider bridesmaid dress styles that have fuller skirts and stretch liner. Those elements will provide room for growth and motion. In addition to comfort, which should always be considered!

Third, if you are breastfeeding or pregnant, we recommend choosing a bridesmaid dress with straps. That way, you will be more comfortable and supported.
Finally, if you will be 8 to 9 months pregnant AT the wedding, pay special attention to the dress length. Some bridesmaid dresses are designed for a maximum height of 5'9 without heels. You may need to order extra length to accommodate for your bump at its fullest, so the dress can be hemmed straight.
