What size should I order in a plus size maternity dress?
Order by your bust and bump measurements, not your pre-pregnancy size, and choose the larger size if you fall between two. Maternity dresses often run one to two sizes smaller than standard US sizing, so check the chart for each dress before you add it to your cart.
Measure your bust at the fullest point and your bump at its widest, then compare to the chart. Pick for the size you will be at the event, not today. If you are unsure, send us a message through the product page and we will help you choose.

Which cuts flatter a plus size maternity silhouette?
An empire waist, a wrap front, or a side tie flatters most plus size maternity shapes because each adds definition above the bump and lets the skirt fall freely. A V-neck lengthens the neckline, and a floor-length or midi skirt moves smoothly without clinging at the hip.
- Empire waist: a seam above the bump that never rides up as you grow.
- Side tie or wrap: adjusts week to week, so the dress keeps fitting.
- Sleeves: flutter sleeves keep arms comfortable; long sleeves suit cooler months.
- Length: maxi for formal events, midi for daytime, both look balanced with flats or boots.
How do you measure for a plus size maternity dress?
Measure your bust, the widest part of your bump, and your hips with a soft tape, then compare each number with the chart for that exact dress. Because bumps change quickly, measure again a week before the event and keep the return window in mind.
- Bust: wrap the tape around the fullest part, level across your back.
- Bump: measure at the widest point, standing relaxed.
- Length: measure from shoulder to where you want the hem, wearing your shoes.
- Between sizes: go up one size, then adjust with a sash or belt.
What colors and prints work for plus size maternity photos?
Solid jewel tones such as teal, wine, and emerald photograph beautifully, and medium-scale florals and palm prints add interest without overwhelming the frame. Avoid very tiny prints that can blur on camera, and pick one color story for the whole outfit so the dress stays the star.
If you are planning bump photos, our what to wear for maternity photos guide covers gowns, colors, and layering. For an everyday base to pair under cardigans, see the over the belly maternity leggings sizing notes.
How do you style a plus size maternity dress for different occasions?
Dress it up with block heels, a belt or sash, and simple jewelry for weddings and parties. Dress it down with sneakers, a denim jacket, or a cozy cardigan for brunch and errands. One dress can work for several events when you change shoes, outerwear, and accessories.
Frequently asked questions
Do plus size maternity dresses run small?
Many do, especially dresses with no stretch at the bust. Our Plus Size Maternity Maxi Gown runs about one size small, and several other dresses run one to two sizes smaller than standard US sizing. Always compare your bust and bump measurements with the chart, and choose the larger size if you are between sizes.
What fabrics are best for a plus size maternity dress?
Lightweight, flowy fabrics with a little give feel best, such as soft knit, modal, and flowy woven polyester. They drape over the bump without clinging. Look for an empire waist or side tie so the fit adjusts as you grow, and a lined skirt for a smooth line.
Can I wear a plus size maternity dress after the baby arrives?
Often, yes. Empire waist, wrap, and side-tie dresses have room that works as your shape changes after birth, and flutter or long sleeves suit nursing-friendly layering. Pick a solid or small print and a classic length, and the dress will work for parties and everyday wear later.
