Now, I know, I might seem weird for doing this, but you're the on who clicked on this guide. What did you expect.

Anyhow, you'll need 5 things:
1. A Jacket- Any Gray Jacket will do, I cant find the one Simon wears

2. A phone- not just any phone, you'll need a Sony Ericsson Walkman W200i. Here's the link, unless you live in china, it will likely take about a month to arrive: https://www.ebay.com/itm/204980285143?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D271655%2C271352%2C272393%26meid%3D943008ec03124d53bb2faed07ecf94aa%26pid%3D101875%26rk%3D2%26rkt%3D4%26sd%3D315721152754%26itm%3D204980285143%26pmt%3D1%26noa%3D0%26pg%3D2332490%26algv%3DSimVIDwebV3WithCPCExpansion%26brand%3DSony%2BEricsson&_trksid=p2332490.c101875.m1851&itmprp=cksum%3A204980285143943008ec03124d53bb2faed07ecf94aa%7Cenc%3AAQAJAAABEKAOBbj8c9I6eO4vPyI9FfMl8NhNqsULUU1TfDUZ7khlEOUs1KvrHrT4gpjyzdcLJrvAgxQSCMKAEBKeSoouzh5mZ6EOmtSxkgiP5sNRc2ObkI5OSBhwR7LKInRqYcyK3wf5BdpXe0AeJluHG6%252Fy2IM7sM3gFw5M5axOOKu5a2m97ZroF48EEO32XksACcoaH%252FM68AzLtM0SGtRb1t9uesYNulS%252FIw23av86db54IHt%252FaeTo7J1cZwzNYjFwX2qrTW8OROvYwwTBKh3iGRQhahFhDreM8uDaqOFICWNeSdvT5WeUr%252B%252FO2sQq3mKPmBauWcYT0z41EYUl3qx%252B7sQlQEjgEZcDPwn6kepuz8QpeCqs%7Campid%3APL_CLK%7Cclp%3A2332490&itmmeta=01J7813PZMPG5NJ0CX62KZXKAD

3. His satchel- it's not very big, don't use this as a backpack substitute Link: https://www.amazon.com/Sweetbriar-Classic-Vintage-Messenger-Bag/dp/B0BFTNF8K5/ref=pd_bxgy_d_sccl_1/134-1018937-4226530?pd_rd_w=OivgG&content-id=amzn1.sym.f7fa8b58-6436-47b8-8741-9e90c231669e&pf_rd_p=f7fa8b58-6436-47b8-8741-9e90c231669e&pf_rd_r=Y7FC22944DR9N8WEA7BQ&pd_rd_wg=mU2GE&pd_rd_r=52ed183d-5247-40b2-a739-045753e520f5&pd_rd_i=B0BFTNF8K5&th=1&psc=1

and just about any sweatpants without flashy colors, and black shoes will do. If you want stuff like a glock 19 (hopefully an airsoft one, don't wave a real gun around on halloween), i'm sure there's plenty on amazon. Hopefully, this guide took you from looking like this
