The bowler hat is the one from Late Night, dehaired, retextured and converted into an accessory for YA females. The lighter suits (which of course turned out the best) wouldn’t be within show regulations yet, but it’s my hope they’ll relax the colour regulations at some point because I love it when riders wear attire that compliments their horse’s colouring. The black ones should comply with the current GBA/SSA show attire rules, possibly the navy one. Preview them in all their unedited-ness here. Non-recolourable sorry, but 3 different suits with a number of waistcoat+tie combos gives you a choice of 9 looks.
Suits are a retexure of an EA outfit, found in full outfits.
