Suede is useful learning position and things like that because they help you stick and not slide around so mucb. Full seat helps you stick better in the saddle and knee patches and chaps help your legs (to an extent) so when I was learning jumping I used them to help my position while I got the hang of it and I find them really useful riding on the flat too. I'm not sure what elite dressage riders use, it might just be a matter of personal preference, but probably they are useful for dressage. I'm not sure if they're made specifially for dressage, though. Some probably are.
Jodhs are so useful for English, you'll love them! Riding gloves are great too (especially on Pita Mr I-don't-care-what-you-think-we're-going-that-way haha) they help with your grip and stop the reins sliding.
What did you give your family? I gave my dad a book on Formula One (he loves racing cars) my mum a book of Thai recipes because she loves Thai food, and my sister hi-bounce balls and a packet of water toys for the holidays.
That sounds like fun! Usually we have a quiet Christmas Day and meet up with our relatives on Boxing Day. We do a little Christmas dinner on 25th and do the big a
Christmas lunch the next day. On 23rd we have our street party with all the neighbours, everyone brings food and drinks and we blockade off the street and have a big party. The kids play games and the adults sit and talk. When it gets dark, we play spotlight through everyone's yards and all around the street.
