I don't think the point is that these are meant to be bought by disadvantaged women. I think that what happens is that for every piece bought, the designer will donate one piece to this charity that gives the clothes to disadvantaged women.
And I don't know about the price difference between the pieces but honestly $109 for a tote doesn't seem horrible to me. I bought Meghan's Everlane tote and it's lasted me a long time and hopefully will last me many years, so to me it's worth it. $120 for a pair of pants is pricey for me, just because my pants don't last that long. Too much washing and wearing. And I wouldn't pay $125 for a white button-down because hello, white button-down. The dress is priced so low I'm wondering what's wrong with it, lol.
Meghan looks basic but very nice in her outfit today. Dark pants, white shirt, heels. You really can't go wrong with that look. And her hair is amazing.
