How to look more put together ?

Hey guys .

So my wardrobe consists of 2-3 jeans and plain T-shirt of the same style but different color .

I'm a new mom and I'm just having the hardest time looking better in clothes . I was like this before baby but now it's like I don't even have time . My weight kind of fluctuates so I've alwAys had trouble with this . I have zero fashion sense when it comes to myself .

Looking for pointers
