Worth it to buy life skill gear for horse training?

I'm at Artisan 8 and just now thought of if I should buy some accessories, crop etc. for my horse training. I've just been using the Trainer's outfit and pearl shop attire.
So, is it worth it? Should I just splurge and buy everything PEN or what is your guys' advice?

 

Couple points, buy TET and not PEN, unless your really have money to burn. As to the question itself, the mastery's useful for breeding by increasing the chance to score a t8 out of t8 and t7. However, it's not so useful for training the horses. A +5 silver embroided trainer set ecplises any bonus the mastery can give. Get that first, it's a degree of magnitude more affordable then shore up the mastery for breeding. Meaning. wear your manos set when you breed horses, switch to silver while training.

 

I see. +5 silver embroided trainer armor has never been sold on the CM, it seems. I loathe enhancing, but that seems to be the only way I can get huh?
As for the other gear, besides getting a TET manos, what do you think I should prioritize getting with the 5 bil I got?
Thank you, btw. Now I finally know how this works
