Does it look bad?

I was trying this outfit, I liked it a lot. I sent this picture to my husband and asked him

If I should buy it, he said nah. At the same time I sent it to my sister and she said “you look fat”. I didn’t buy it. I still like it, but those comments made me uncomfortable dressing like that. I have a baby and still trying to loose weight, but I’m not disciplined with my diet yet...
