Salaam - Need Advice About Wearing Hijab in School This Ramadan

Salaam sisters! After a lot of thinking and going back and forth with myself, I've decided I want to wear my hijab full-time starting this Ramadan - it'll be my first Ramadan as a revert. I do have a few practical worries and was hoping for some advice from you all. First, my school uniform is awkward. Skirts have to sit roughly at the kneecap, and everyone kind of rolls them up. In winter I wear opaque tights so it's fine, but in summer I don't know what to do. Letting the skirt down full length can lead to teasing, and wearing trousers would also get me picked on. My only thought is something like flared yoga-style pants that still look modest but are cooler - has anyone tried that or found other solutions that work in school? Second, hijabs around my ears and neck get really hot for me - I have sensory issues, so anything close to those areas in heat is super uncomfortable. Do you have hijab styles or fabrics that feel light and breathable while still giving good coverage? Third, I'm in the UK and our summers can feel oppressively hot for me (I literally need multiple fans to stay comfortable). PE is the biggest worry - running around fully covered is tough. Has anyone negotiated alternative PE clothing with a school (like a modest sports hijab, long-sleeve sports top, or lightweight tracksuit bottoms) or found ways to manage during lessons? Any tips on fabrics, styles, school-friendly modest options, or how to speak to school staff about reasonable accommodations would be so helpful. JazakAllahu khairan for any help or personal experiences you can share 🙏
