Some bling is fine for me, but in moderation. I usually ride in a plain leather hunter bridle with raised nose and browband, with a little sparkly blue ribbon charm on the off side. I'm not a "sparkly gal" myself, and started leaning toward English showing because of the more conservative show attire preferences, but a little can be fun (I do pull the charm off before my show classes!). I also ride a gelding, and I feel a bit sorry for him covered in Swarovski Crystals and glitter. A friend of mine runs barrels with a pink saddle pad and a matching pink and clear crystal bridle and breastcollar. The whole ensemble sat on a palomino gelding. I guess I just have this weird idea that geldings appreciate more conservative tack (sorry for anthropomorphizing) and mares can pull off the more blingy tack.
The bling browbands on the dressage bridles do look cool!
