What tips are there to widen a dress?

  1. One of the simplest methods is to take advantage of the seam allowance. By slightly unpicking the seams on the sides, you can gain a few precious centimeters to enlarge a dress. If that’s not enough, consider adding fabric to the dress. Choose a matching fabric or play with contrasts for an original transformation!
  2. For those looking for tips to further widen a dress, adding an elastic panel to the back is a clever solution. It provides comfort and helps maintain a cohesive design. 
  3. Another option is to transform the back of the dress with an eyelet closure. This solution requires the most creativity and skill; however, the result adds details to the dress with neat finishes. It is especially worth considering for evening, gala, or bridal dresses!

With a little patience to sew these pieces, you will have a custom-made dress. And if sewing isn't your strong suit, no worries: there are many online tutorials to guide you in your alterations.

How to adjust the back of a dress?

Is the back of your dress too tight? Here’s how to adjust it. 

  1. Unpick the seams under the arms and insert a piece of fabric to enlarge the dress. This method is discreet and allows you to gain a few centimeters.
  2. Shorten the zipper and insert eyelets for a corseted back. With this solution, you transform the cut of your dress with style!

Which fabrics to choose to enlarge a dress?

The choice of fabric is crucial for a successful alteration. Opt for a new fabric similar to that of your dress. Materials like cotton or silk are ideal for their flexibility. A soft fabric will adapt better to the cut and provide an aesthetic finish. For a unique look, feel free to choose a dynamic print or a contrasting color!

How to make alterations on a dress?

Making alterations may seem intimidating, but with the right sewing tools, it's a hobby within everyone's reach.

A sewing machine greatly facilitates the work, but it is also possible to sew by hand. This skill will allow you to make precise and personalized adjustments.

  1. Start by adjusting and pinning the desired modifications.
  2. Then, move on to sewing by removing the pins one by one.
  3. In the end, iron the seams to flatten them and achieve a professional finish.
  4. Wash the dress before wearing it.

How to prevent the dress from being too tight?

To avoid your dress being too tight, anticipate by checking the measurements before purchase. If you are between two sizes, it is often better to choose the larger one for more ease. You can also choose models with an elastic panel or in stretchy materials for more comfort. The key is to feel free in your movements! Remember that well-fitted clothes enhance your body in a harmonious way. 


At Les Petits Imprimés, we understand the importance of an outfit that fits you perfectly. Whether for work or an evening out, a well-fitted dress is the key to a successful look. Feel free to explore our collections to find the piece that will suit your desires!
