It sounds like you're looking for a trendy pair of bottoms that combines several distinct style elements! Here's a breakdown of what "Slim High Waist Capris Sexy Bell Bottom Flare Tights Solid Hot Y2k" typically refers to:

• Slim High Waist Capris: These would be leggings or tight-fitting pants that end below the knee (capri length) and have a high waistband that sits above the natural waist. The "slim" aspect indicates a close fit through the thighs.
• Sexy Bell Bottom Flare Tights: This describes the leg shape. Starting slim at the top (the "tights" part), they then flare out from the knee downwards, creating a bell-bottom or flared silhouette. The "sexy" suggests this flare is designed to be flattering and eye-catching.   
• Solid: The garment will be in a single, uniform color.
• Hot Y2k: This points to a style influenced by the fashion trends of the late 1990s and early to mid-2000s (the Y2K era). In this context, it might imply a bold, possibly slightly retro, and definitely attention-grabbing design.

Putting it all together, you're likely envisioning a pair of high-waisted capri leggings that are slim through the upper leg and then dramatically flare out into a bell-bottom shape below the knee. They would be a solid color and have a distinctly trendy, possibly slightly edgy, Y2K vibe that's considered "hot" or very stylish.

Given that it's late spring in Poland, these capris could be a fun and fashionable choice for the current weather. The capri length is perfect for the milder temperatures, and the combination of a slim fit with a dramatic flare is very on-trend. The high waist is flattering, and the Y2K influence adds a unique and playful touch to your outfit. You could pair them with platform shoes or chunky sneakers to further enhance the Y2K aesthetic.
