Little Mix criticized for risque outfits at Ariana Grande's Manchester benefit concert

Little Mix fans are miffed.

The British girl band is facing heat for their revealing outfit choices at Sunday night's all-star concert to benefit the victims of the attack outside Ariana Grande’s Manchester concert last month.

Many viewers felt their outfits were "distasteful" in light of the reason the concert was called.

Singer Leigh-Anne donned a bra instead of a shirt while her fellow singers, Jesy Nelson and Jade Thirlwall, chose leotards with thigh-high boots. Perrie Edwards was slightly more covered up with a fringe piece she wore over her leotard.

However, other fans came to the group's defense:

Grande's One Love Manchester concert Sunday raised more than $13 million for the We Love Manchester Emergency Fund, created for those affected by the attack at Grande's May 22 show.
