To pull together a relaxed casual ensemble with a modernized spin, marry a dark purple crew-neck sweater with a grey sweatshirt. For something more on the casually edgy side to complement this look, complement this getup with low top sneakers. As you can see, this getup is a really wonderful idea, especially for summer-to-fall weather, when the temperatures are dropping. If you're often not sure how to dress appropriately for your age, this getup is a vivid example.
