Chicago in December: What to Wear at RSNA 2020
Chicago’s early-winter weather calls for practical layering, comfortable footwear, and protection from wind. Around the RSNA 2020 Annual Meeting dates, 29 November through 4 December, temperatures could shift from crisp and dry to snowy, wet, or sharply cold within a single day.
Radiology professionals traveling for meetings, networking, or local events needed clothing that worked across several settings. A polished outfit suited to presentations and professional gatherings, while warm outerwear and weather-resistant shoes made the walk between hotels, transport stops, and the convention area more comfortable.
Packing for Chicago also meant preparing for heated interiors. Hotels, restaurants, meeting rooms, and exhibition spaces could feel substantially warmer than the streets. A flexible wardrobe was therefore more useful than a single heavy outfit.
Typical Early-Winter Conditions
December in Chicago is usually cold, with daytime temperatures often hovering around freezing and evenings becoming considerably colder. Wind coming off Lake Michigan can make the air feel harsher than the thermometer suggests, particularly near the lakefront and open streets.
Snow is possible, although conditions can vary from clear pavement to slush or icy sidewalks. Rain, melting snow, and puddles are also common concerns. A waterproof or water-resistant outer layer helps keep business clothing dry during short journeys between accommodation and event locations.
Daylight is limited in early December, so morning departures and evening returns may take place in darkness. Reflective details are not essential for business attire, but a dark coat paired with visible accessories and practical shoes improves comfort and visibility.
The Essential Layering System
Start with a breathable base layer, such as a lightweight merino wool shirt, thermal top, or moisture-wicking long-sleeved garment. This adds warmth without creating bulk beneath a blazer or suit jacket. Cotton shirts can work indoors, but they are less effective if exposed to damp weather for long periods.
The middle layer should match the day’s schedule. A fine-gauge sweater, cardigan, fleece vest, or tailored knit jacket can be removed when entering a heated venue. For formal appointments, a wool blazer or structured jacket provides a professional appearance while adding insulation.
Finish with a warm coat that reaches at least the hips. Wool overcoats suit business attire, while insulated parkas offer stronger protection in snow and wind. Choose a coat with a high collar, secure pockets, and enough room for a jacket underneath without restricting movement.
Business Attire That Travels Well
For men, a dark wool suit with a long-sleeved shirt and a thin sweater or thermal layer offers a reliable foundation. A wool or cashmere blend tie can add warmth without looking overly seasonal. Dark navy, charcoal, and black also hide minor splashes from wet sidewalks.
For women, trousers, a knit dress with opaque tights, or a skirt paired with warm hosiery can work well. A tailored jacket, soft turtleneck, or fine sweater provides professional polish while allowing easy adjustment indoors. A silk or wool scarf adds color and warmth without taking up much space.
Choose fabrics that resist wrinkles and dry relatively quickly. Merino wool, wool blends, technical trousers, and wrinkle-resistant shirts are useful for travelers moving between hotel rooms, restaurants, and professional appointments. Pack a second shirt or blouse when a full day includes commuting in wet weather.
Shoes, Socks, and Cold-Weather Accessories
Footwear is one of the most important decisions for a December stay. Leather ankle boots with sealed seams, rubber soles, and good traction can complement business clothing while handling light snow and rain. Weatherproof dress shoes may work in dry conditions, but smooth soles can become uncomfortable on icy pavement.
Bring at least two pairs of professional shoes so each pair can dry and recover between uses. Cushioned insoles help during long periods of standing or walking. Wool or wool-blend socks are warmer than thin dress socks and help manage moisture inside boots.
Useful accessories include insulated gloves, a warm scarf, and a hat that covers the ears. A compact umbrella can help with rain, but it should not replace a proper coat hood in strong wind. A small water-resistant bag protects documents, electronics, and identification while moving through wet conditions.
Packing Choices for Different Hotel Stays
Hotel location and daily routine affect how much outerwear and footwear travelers need. Someone staying close to the meeting area may spend less time outdoors, while guests commuting from a farther property may need stronger protection against wind, snow, and changing temperatures.
Accommodation categories can also shape packing space and convenience. Travelers comparing 3-star and 5-star hotels may find that room amenities, storage, and access to facilities influence whether bulky winter items are easy to manage.
| Clothing item | Practical choice for Chicago in December | Why it helps |
|---|---|---|
| Outer coat | Wool overcoat or insulated waterproof parka | Blocks cold, wind, and light precipitation |
| Mid-layer | Merino sweater, cardigan, or tailored jacket | Adds warmth and can be removed indoors |
| Base layer | Thermal top or breathable long sleeve | Keeps the body warm without excess bulk |
| Trousers or skirt | Wool trousers, lined trousers, or warm tights | Provides insulation during outdoor walks |
| Footwear | Weather-resistant boots with traction | Handles slush, puddles, and slick sidewalks |
| Accessories | Gloves, scarf, ear-covering hat | Protects exposed areas from wind chill |
A Practical Outfit for Each Day
For travel days, wear stretch trousers, a breathable base layer, a sweater, and a weatherproof coat. This combination is comfortable during transit and presentable enough for an informal meal or hotel appointment. Keep gloves and a scarf in an accessible pocket rather than at the bottom of a suitcase.
A formal meeting day calls for a suit, tailored separates, or a professional dress with warm tights, paired with a long coat and practical shoes. Carry indoor shoes if winter boots are needed for the commute. This simple change keeps the main outfit clean and comfortable.
For evening receptions or dining, use the same base pieces with a refined accessory: a patterned scarf, polished belt, statement earrings, or a textured sweater. Dark colors coordinate easily, allowing several outfits from a small selection of garments.
A Compact Cold-Weather Packing List
- One warm, water-resistant coat with secure pockets
- Two professional outfits suitable for meetings or presentations
- Two breathable sweaters or mid-layers
- Weatherproof boots plus a second pair of indoor shoes
- Warm socks, gloves, scarf, and an ear-covering hat
- A compact umbrella and a protective bag for electronics
Clothing for RSNA 2020 needed to balance professional appearance with Chicago’s demanding winter conditions. Build outfits around layers, protect your feet from wet pavement, and leave enough flexibility to adjust once you move indoors. Review the forecast shortly before traveling, then finalize outerwear and footwear according to the latest conditions.
