Alright, let's talk about this 1688 seller — 常熟市虞山街道赵公子服装商行 (Zhao Gongzi Fashion Firm). They're a small-ish shop with 33 products, mostly tops and outerwear. The name sounds fancy, but the numbers are pretty solid. Let me break it down for you.

What they sell
Mainly sweaters, polos, quarter zips, and jackets. Their top saved items are the Classic Fit Mesh Polo, Quarter Zip, and Harrington Jacket. Looks like they're going for that smart-casual vibe.

Shipping to agent (warehouse)
This is the domestic leg — from seller to your proxy warehouse in China. Average dispatch is a speedy 0.9 days, and delivery to warehouse takes about 1.2 days. That's damn fast, honestly. Your agent will have these in hand quickly.

Reviews & feedback
Only 3 total reviews, so the sample is tiny. But what's there is glowing. One buyer on the Cable Knit Sweater said the fit, embroidery, and color are all on point. For the Quarter Zip, two buyers raved about durability and quality — even after washes it holds up. No defect records either, which is a good sign.

The good & the bad
✅ Pros:

Perfect 5.0 rating (from those few reviews)
Zero defect products
Blazing fast dispatch and warehouse delivery
Positive buyer feedback on quality and fit

⚠️ Cons:

Only 3 reviews — you're kinda betting on a small sample. Not a red flag, but keep that in mind.
No recent negative reviews to judge customer service or return process.

Verdict
This seller looks promising for unbranded tops and outerwear. If you want a quick ship to your agent and solid quality based on early feedback, worth a try. Just don't go all-in until you see more reviews pile up. Solid find for proxy buyers.
