It is generally not necessary to wear clothing under swimwear, as swimwear is designed to be worn on its own. Wearing clothing underneath can make it uncomfortable and may affect the fit and function of the swimwear. However, some people may choose to wear a cover-up or rash guard for added sun protection or modesty. Ultimately, it is a personal choice and depends on individual preferences and the specific situation. **

It is not necessary to wear swimwear under regular clothing. Swimwear is designed for use in water activities and may not provide the same level of comfort or support as regular clothing. Additionally, wearing swimwear under regular clothing may cause discomfort and restrict movement. It is best to wear appropriate undergarments that are designed for everyday wear. **

Sunscreen products that do not contain avobenzone are less likely to cause yellowing of clothing. Avobenzone is a common ingredient in sunscreens that can react with minerals in hard water and laundry detergent, leading to yellow stains on clothing. Look for sunscreens that use alternative UVA filters like zinc oxide or titanium dioxide to avoid this issue. Additionally, choosing a sunscreen that is water-resistant and allowing it to fully dry before getting dressed can also help prevent yellowing of clothing. **

To remove yellow sunscreen stains from clothing, you can start by gently scraping off any excess sunscreen with a spoon or butter knife. Then, apply a pre-treatment stain remover or liquid laundry detergent directly onto the stain and let it sit for a few minutes. After that, wash the clothing in the hottest water temperature recommended for the fabric, and check the stain before drying. If the stain persists, repeat the process or consider using a stain remover specifically designed for oil-based stains. **

Sunscreen products that are labeled as "stain-free" or "non-staining" are less likely to cause yellow staining on clothing. Look for sunscreens that are specifically formulated to be easily absorbed by the skin without leaving a residue that can transfer onto clothing. Additionally, mineral-based sunscreens, such as zinc oxide or titanium dioxide, are less likely to cause staining compared to chemical sunscreens. It is always a good idea to allow the sunscreen to fully dry and absorb into the skin before putting on clothing to minimize the risk of staining. **

No, black clothing does not necessarily attract the sun. Instead, black clothing absorbs more sunlight and heat compared to lighter colored clothing. This means that wearing black clothing can make you feel hotter in direct sunlight, as it absorbs more of the sun's energy. However, the color of your clothing is just one factor in how much heat you feel - other factors like fabric type, fit, and the environment also play a role. **
