How to Shrink a Bathing Suit

To shrink a bathing suit you’ll need to soak your suit in hot water, put it through the hottest cycle inside your dryer, repeat the same operation 2-3 times, then enjoy the new smaller size of your bathing suit.

Some would add ironing the bathing suit, we’ll explain this method in the next section, read through.

Here’s How to Shrink a Bathing Suit:

1. Turn your bathing suit inside out to protect the outer pigments from potential damages.

2. Wash your bathing suit by hand, removing oil, grime and dirt. In this step, you’ll need to use a mild detergent, wash the suit in soapy water, and rinse it with fresh water until there are no suds remaining. 

3. Boil water in a pot, and soak the suit in the boiling water.

4. Wait until the water with the suit inside it cools to the room’s temperature. (This step takes approximately 15-25 minutes)

5. After the suit cools down, use the highest drying settings on your dryer, and the longest drying time (60-70 minutes), then put the suit into the dryer and turn it on. This allows for the highest level of heat that can cause the shrinkage we’re looking for.

6. Repeat this process 2-3 times (max), but only do step 2 once as you won’t need to clean it every time you expose it to heat.

7. Put on your suit after it has completely dried, and enjoy the improved bathing suit size.

How to Shrink a Nylon Bathing Suit

To shrink a nylon bathing suit you’ll most probably need to iron it.

Turn your bathing suit inside out and start ironing all over the areas you want to shrink.

The heat produced by the iron will cause the fibers to contract, decreasing the overall size of the bathing suit.

Some users applauded using the steam setting on their iron, as it helped shrink the bathing suit more than regular settings.

However, always start slow with the ironing settings, then increase the heating settings gradually for additional shrinking if needed.

How to Shrink a Polyester Bathing Suit

Shrinking polyester bathing suit is similar to shrinking nylon bathing suit as well.

You’ll need to turn the polyester bathing suit inside out, clean it thoroughly with laundry detergent, rinse off the water, put it in the dryer that’s put on the highest settings, then re-do the same steps (without the cleaning) one or two more times.

However, the polyester bathing suits have less probability of stretching (don’t worry, we’ll provide you with tips to help against the stretching of bathing suits), meaning you’ll less likely need to shrink a polyester bathing suit than to shrink a nylon bathing suit.
