If you're looking for a casual street style but also sharp ensemble, consider pairing a white long sleeve shirt with a grey tank. You can get a little creative in the footwear department and spruce up your look by finishing off with dark brown leather chelsea boots. Seeing as the weather is getting colder every day, this outfit seems a viable option for the time in between seasons. If you're not sure how to dress in your 20s, this outfit is a great illustration.
