The topic at hand is about finding the best ways to keep your shirt tucked in neatly when you have an ostomy. This can be a bit tricky because you want to avoid putting pressure on or blocking the ostomy pouch. Here are some helpful tips and suggestions from others who have faced the same challenge:

1. Consider using a Horizontal Stealth Belt, which is especially recommended for those with a urostomy. It might also work well for some people with a colostomy or ileostomy.

2. Many people prefer wrap-style ostomy belts made of soft fabric. These are often more comfortable and provide a smoother look under a tucked-in shirt compared to rigid guards.

3. Look into stoma guards or protectors. You can find a variety of designs online by searching for "stoma protectors and covers." The best choice will depend on your body shape, where your stoma is located, and what feels comfortable for you.

4. Some products and sources that have been mentioned include:
- PeskyHernia.com for men's ostomy items like belts and guards.
- Nu-Hope support belt, which can be worn under your trousers.
- Ostomy Secrets support stocking, which is worn over the pouch and pants to keep the pouch flat.

5. Level 1 support boxers, which are stretch fabric underwear, can be paired with high-waist trousers. This combination helps secure the pouch, offers mild hernia prevention, and allows you to tuck in your shirt without needing extra gear.

6. Suspenders, also known as braces, can be a great alternative to a belt. They keep your trousers up without squeezing the pouch, and many find them very comfortable and suitable for keeping shirts tucked in.

7. Some people choose to skip fully tucking in their shirts for comfort. Instead, they might wear sweaters, leave T-shirts untucked, or use support garments like the Nu-Hope belt or Ostomy Secrets stocking. When dressing formally, they might only partially tuck in the outer layer.
