Going out outfits

Okay so I haven’t bought anything for myself since my daughter was born and that was almost 3 years ago. A close friend of my husband and mine is coming up next weekend and we are planning on getting a baby sitter and going out for dinner and drinks and I have nothing in my closet besides yoga pants and tank tops. So I’m looking for inspiration on going outfits. I’m finally down to a size 4 from a size 12 so I’m wanting to show off my weight loss because most of my clothes are big on me now.
