Whether it is inappropriate to wear a see-through swimsuit in a pool largely depends on the cultural and social norms of the particular context in which you find yourself. In some cultures or social settings, it may be considered acceptable or even fashionable to wear see-through swimsuits. In other cultures or settings, it may be seen as inappropriate or offensive.

1. The setting: Is the pool public or private? Is it a family-friendly environment or an adult-only area?
2. The dress code: Are there any specific rules or guidelines about what is considered appropriate swimwear in the pool?
3. The cultural and social norms: What are the cultural and social norms in the region where the pool is located?
4. The comfort level of others: Even if there are no specific rules against wearing a see-through swimsuit, you may want to consider the comfort level of others around you.
