At around 0:30 in the video, she steps back far enough for me to read the bottom word, Nutrishop, which brings me to their apparel shop. The specific logo on the shirt appears to be a match for their camo training shorts, so I suspect that the shirt was purchased from the same company. Since their products seem to appeal to a "pro-Americana" stance with American flags on their merch and multiple "military"-themed items and many different camo patterns, the shirt probably does say "United We Stand".
TL;DR: The shirt likely reads "United We Stand", and she's enough of a regular shopper at Nutrishop (a vitamin supplement store) to buy a shirt from them with their logo on it.
Looks to me like it says "United We Stand". But the cleavage is distracting so it's tough to make out the words.
