When in doubt , wear something that is versatile and can be worn in multiple ways. I found this dress shirt and I think it's the perfect addition. I always love a good peplum, but when it's less fitted - more loose and even comfier - I love it even more.
If you decide to go for something similar, just keep in ming to balance the look with something very fitted on the bottom half. Whether is a pair of legging as I am wearing, tights or even bare legs, it's best to play it safe. Otherwise, there might be a chance of looking like a cotton ball - perfectly round ;)
