Hi Purple Celebrating 25! 
I discovered your item on Writing.com via random Read & Review and am sending the following feedback for your consideration.
Positives
I really loved Peggy's character and how excited she got at the thought of an 80's party. The dialogue exchange with Scott was realistic and kept the story moving along nicely, giving the reader a sense of momentum to the narrative after establishing the clothes that she chose.
Suggestions
The ending line could have been a little better. With very short flash fiction stories like this, I often look for something to really punctuate the read, and a line where Peggy just kind of muses to herself that she's going to look great left me wanting a little bit more in the way of an ending.
Overall
Overall, this was a well-written piece (no surprise, coming from you!) and a good take on the prompt. DFFC prompts are not always easy to incorporate and I thought you did a great job. Nice work!
I hope you've found this review helpful. If so, please consider paying it forward by reviewing the work of another Writing.com author! 
Sincerely,
Jeff
