Guangzhou Tianna Garments Trading Company

If you're shopping on 1688 for underwear and loungewear, 广州天纳服装商行 is a name that keeps popping up—and for good reason. This is a small but focused store (21 products, all in Swim & Intimates), and it's sitting pretty with a 4.9 seller rating. But let's not get carried away; let's break down what's actually going on here.

What they sell:
Think everyday basics—boxer briefs, trunks, stretch cottons, and tech pants. The top saved items are Modern Cotton, Trunk, and HeatGear, which tells you this place is all about comfort-first, no-nonsense gear. You're not coming here for flashy prints or weird cuts; you're coming here for stuff you'll wear on repeat and forget you're wearing.

Warehouse Delivery Vibe:
Here's the thing to keep straight: the shipping time you see is just the domestic leg—from the seller to your proxy warehouse in China. This store is lightning fast on that front. Average dispatch time is 0.5 days, and average delivery to the agent warehouse lands at 1.1 days. That's basically blink-and-it's-there speed. Once it hits your agent's warehouse, the international journey is a whole different story depending on your line, so don't get tripped up on that.

The Good & The Bad:
Let's start with the good. Zero defective products reported, which is a clean bill of health. The 28 reviews are all positive, and people are talking about solid build quality and real durability. One review on the Greca Border stuff (which looks like a solid brief) mentions the price is a touch higher than budget options, but says it'll "easily survive a full season of heavy abuse"—that's a workhorse endorsement if I've ever heard one.

The Modern Cotton line is getting love across colors—grey, black, you name it. People are saying the fabric is smooth, the waistband doesn't dig in, and the stitching holds up. One guy even mentioned he'd "definitely buy another pair." The Trunk gets a thumbs up too, though there's a fair warning: the fabric runs a bit thin, and the inside tag can annoy you. Easy fix, just snip it off, but worth knowing.

Now the honest stuff. There's no hidden defect pile, and returns aren't a concern based on the data. But this isn't a huge store with thousands of reviews—28 reviews total means you're dealing with a smaller, more niche seller. That can be fine, but it also means less crowd-sourced feedback to lean on. Also, a couple of reviews on the Cotton Stretch and Modern Cotton are almost word-for-word identical, which is a little suspicious. Could be a repeat buyer pasting the same note, or could be a bit of review padding. I'd keep that in the back of my mind.

Bottom line:
If you're after basic, comfortable underwear that ships to your agent in about a day and doesn't fall apart, this is a solid find. Just don't expect luxury thickness on the Trunk, and be ready to cut out that tag. The 4.9 rating isn't a fluke—this seller is doing the basics right. For an add-on item to a bigger haul, it's a safe bet. For a full wardrobe overhaul? Maybe wait until they get more reviews under their belt.
