Great — here are reliable online places to buy trendy winter clothes this season in New York, organized by type so you can pick what fits your style and budget. I’ve included quick notes (shipping, speed, returns or perks) and reputable sources.

Department stores / fast delivery

• Nordstrom — wide selection (designer to mid-price), easy returns and multiple shipping options for US customers. (nordstomstyles.com)
• Bloomingdale’s — department-store mix of contemporary and designer labels; online orders deliver across NY and often offer store pickup. (net-a-porter.com)

Affordable / fast-fashion

• Zara — on‑trend seasonal outerwear and layering pieces; home delivery and store pickup options in the U.S. with next‑day / 2–4 day choices depending on option. (Zara.com)
• ASOS — huge trend-driven assortment (brands + in-house styles) with standard and express shipping to U.S. addresses; good for quick, inexpensive buys. (ASOS.com)

Basics / sustainable essentials

• Uniqlo — functional winter essentials (heattech, light down) and a reliable online store serving NYC shoppers. (Uniqlo also has major NYC locations for pickup/returns.) (ny.eater.com)
• Everlane — quality minimalist sweaters/coats and transparent/sustainable sourcing; straightforward U.S. shipping policy (free standard shipping often available). (everlaned.com)

Outdoor / performance winterwear

• REI — insulated jackets, snow-ready layers, boots; strong selection for cold/wet weather and free US shipping thresholds + store pickup at local REI. Good for technical cold-weather gear. (rei.com)
• Patagonia / The North Face — for high-performance parkas and technical layers (both have U.S. e‑stores and reliable shipping).

Luxury / designer

• NET‑A‑PORTER / Mr Porter — top designer coats, knitwear and fast delivery options in NYC (Premier/same‑day or next‑business‑day services available in NYC area). (net-a-porter.com)
• Farfetch / Saks / Neiman Marcus — marketplace selection of designer winterwear and expedited shipping options.

Resale / rental (trend-forward, budget or sustainable)

• The RealReal / Depop / Poshmark — secondhand designer & vintage finds at lower prices.
• Rent the Runway — rent high-end coats or statement pieces for events instead of buying.

Local NYC boutiques & indie brands (shop online + support local)

• Many NYC boutiques and emerging labels sell online (search neighborhood boutiques — West Village, SoHo, Williamsburg shops often post seasonal drops). For unique trendy pieces and small‑batch coats, check independent boutiques’ webstores or Instagram shops.

Quick shopping tips for New York buyers

• If you need something fast: look for same‑day/next‑day delivery, in‑store pickup, or retailers with NYC “Premier” services (Net‑A‑Porter, some department stores). (net-a-porter.com)
• Check return windows before buying (fast‑fashion vs. department stores differ widely). (nordstomstyles.com)
• For technical cold-weather gear (snow, wind), prioritize outdoor retailers (REI, Patagonia, The North Face). (rei.com)
• Consider resale/rental for trendy statement pieces you’ll wear only a few times.

If you want, I can:

• Narrow these to a short list by budget (under $150 / $150–500 / $500+), or
• Find currently available coats/sweaters in your size and price range from 3–5 of these stores and show exact items (I’ll pull live listings).
