She races in the same Spyder USST suit, which has a white background as the rest of the USST women speed skiers. MS normally races in red superhero suit....all events.
Spyder pays the USST a lot of money for that deal. The only suits that an Anerican athlete races in, an a WC event, are the approved team suits. And, yes, they are all tested.
Now, as part of "the deal", LV has a bunch of training suits, some black, most white, which prominabtly display the gold logo of the LV Foundation. Not a "team suit", per se. Same material, same construction and build quality. No racing.
Are you certain of this? Pretty sure LV has a series of her own suit designs she races in. E.g. check out what she wore in France....it's her signature pink/blue with stars on forearms/lower legs and her LV logo. (I only know this as my daughter skis in the LV model suit that while not exactly the same as the one LV wore in France, is clearly of the same design). Haven't seen any other women in a suit with that particular design.
Mancuso also had a suit that was different than the others if I remember correctly as well.
No doubt there is a team version LV can wear, but seems like she has her own line to race in as well. (which has been the case in prior years).
