It seems like you’re referring to “T-shirt design discretion” in some way, but I’m still not quite clear on your meaning. If you’re asking about designing T-shirts with careful consideration or discretion, here are a few ideas that might help guide your process:

1. Audience Awareness: Make sure your design is suitable for your target audience. Whether it’s a specific age group, profession, or interest group, the design should resonate with them.

2. Appropriate Imagery and Language: Be mindful of the images or words you use. Ensure that they align with your brand or message, and avoid controversial or offensive content unless it’s part of your intention (and is handled with care).

3. Simplicity: A clean, simple design is often more effective and versatile than something overly complicated. A minimalist approach can be powerful and widely appealing.
