это не симбиоз, Вам же написано на чистом английском языке:
Next, a zippered hoodie without a lot of bulk is a necessity. While Urban Outfitters has several decent choices, such as the Penguin Secret Sam hoodie or the Industry reversible striped hoodie, we like the simplicity of American Eagle's Signature full-zips. The colors are easy to work with -- brown, black and gray -- and they're priced right. Leonard prefers to wear earth tones, so go brown.
You then need to add lightweight outerwear in the form of a blazer or plain military-type jacket. Urban Outfitters carries a perfect military moleskin jacket from Spiewak in gray that features a stand-up collar and epaulets. Those details, including buttoned plackets, add just enough oomph to keep things interesting. Unfortunately, things get boring from the waist down -- isn't that always the way for geeks? -- and Leonard hits the snooze bar with nondescript jeans and Converse All-Stars.
Отдельно hoodie, отдельно military jacket.
