Do I need to size up for a romper?

When you’re in between sizes, go up a size if you’re in doubt. Stretchy jumpsuits don’t have to have a narrow fit, so going up a size can enhance comfort and improve the drape on your lower half. Jumpsuits frequently run short in the torso and are prone to cling on the bum.

Once you know the right size of rompers, the next thing is to choose the following. 

 1. Fit

A specific romper size could come in both tight and loose-fitting options. Not everyone prefers tight-fitting clothes, and in that case, you’ll probably want to size up. On the other hand, if you want a close fit, you could size down if your exact size doesn’t feel snug enough. 

The coziest fit will also depend on where you’ll wear your rompers. Is it for a party or just wearing it in the house? This could help you determine the ideal fit for your rompers.

2. Design

There’s a wide variety of romper styles on the market. Sleeveless V-necks are a popular adult romper design, but some people prefer having sleeves. The exact design of your rompers will depend on how you want the top to look. The shape of the neckline, the length of the sleeves, and the length of the shorts are necessary considerations. 

3. Color

Next, you should think about the best color for your rompers. Do you prefer bright-colored clothes or dull ones? Your mood can also dictate the best color to wear on a particular day. 

You’ll also have to decide on a solid color or a decorative pattern. A solid color could do the trick if you don’t want all the attention in the room. However, you can choose rompers with a lovely pattern if you want something flashy.

4. Fabric

It would help if you also chose between natural fabrics and synthetic fabrics for your rompers. The type of fabric will determine the level of comfort you feel from your rompers. The fabric also affects the ease of cleaning your outfit. Materials like cotton are tough enough for both hand and machine washing. If you get rompers made from delicate fabrics, you might have to dry clean them.
