There’s benefits with both, online because I don’t have to leave the house, they have great deals and some stores I can buy from where there isn’t an actual store where I live.
the problem with buying online though is if it doesn’t fit, it’s expensive as hell to send back, so I usually don’t send it back & just keep the clothes & either try to lose weight to fit into them or give them to my skinny friends.
I guess the benefit of in store would be being able to try the clothes on before you buy them, but half the time they don’t have my sizes 🙄
