MLB Multi-Color T-Shirt Collection Review: 100% Cotton, 30+ Colorways, S–XXXL

The MLB Multi-Color T-Shirt Collection (SKU 7718818098) is a short-sleeve cotton crewneck sold through a single Weidian listing that carries more than thirty colour codes. At $7.91 USD, down from a listed $8.45, it is positioned as an everyday printed tee rather than a premium piece. We ordered a sample at the listed price and ran it through our standard apparel checks before writing this.

What we ordered and how we checked it

The listing is unusual in one respect: the product is not a single shirt but a colour matrix, so the sample we received only tells us about the cut and construction shared across the range, not about every print in it. We tested accordingly.

• Logged the packaging condition on arrival, including whether the tee was bagged flat or folded hard enough to crease the print area.
• Weighed the sample on a digital scale to sanity-check the stated 180–250 g knit weight.
• Measured chest, body length and shoulder flat, then compared those numbers with the listing's stated 1–2 cm tolerance.
• Checked print registration and edge sharpness against the reference photos, plus stitching at the neck rib and hems.
• Machine-washed one colourway cold, air-dried it, and re-measured to see how the cotton moved.

What a home setup cannot confirm is the gram-per-square-metre figure itself; a kitchen scale weighs a garment, not a square metre of knit. Treat the 180–250 g range as a plausible mid-weight band rather than a number we independently verified.

Fabric and the antibacterial claim

The listing gives the main fabric as pure cotton and the material composition as 100% cotton, with printing as the only decoration. In hand, the knit reads as a normal mid-weight jersey — not the thin, slightly transparent cotton you get on sub-$5 blanks, and not a heavy loopback either. The seams and neck rib were tidy on our sample, and the print sat flat without the plasticky ridge that shows up on cheaper transfers.

The material function field lists an antibacterial finish. That is a catalogue claim with no supporting documentation in the listing, and we have no way to test it. We would not factor it into a purchase decision.

Sizing is the real open question

This is where the available evidence conflicts and where you should slow down. One buyer commentary on the MLB brand describes its apparel as running looser than standard sizing, with shoppers routinely sizing down. A separate buyer report describes MLB-branded tees made by Nike running small, with a regular size L wearer needing an XL.

Those two accounts cover different garments from different supply chains, so neither settles this listing. Our flat measurements on the sample landed inside the stated 1–2 cm tolerance, which confirms the listing is internally consistent but says nothing about how the tee drapes on a body. The tiebreaker remains the listed chest measurement compared against a tee you already own and like.

What the 40-plus colour codes actually cover

Despite the collection framing, the range is narrower than the code count suggests: the overwhelming majority of options are a black or a white base with a printed letter or geometric motif.

The practical takeaway is that choosing the right code matters more than choosing the right shirt, because a 903 black and a 948 black are not the same garment. Confirm the variant against its own image set before ordering, since the shared listing photos do not map one-to-one onto the codes.

Care, and the one complaint worth reading

The only care-related evidence in this category is negative and comes from a different MLB garment, so weigh it accordingly — but do not ignore it. A customer of the MLB official flagship store reported that a purchased top shrank severely after being washed once, and that service declined to help on warranty grounds.

"I bought a sweatshirt from the MLB official flagship store on Taobao on 25 August 2025. It felt good when I tried it on, so I washed it. I never wore it again. A month later I took it out and found it had shrunk badly. Customer service ignored my request and only kept repeating that it was past the warranty period."

Our cold-wash and air-dry test on one sample produced no visible change in length, which is consistent with the claim that the failure mode is heat, not cotton itself. No care instructions are printed in the listing, so that complaint is the closest thing to guidance available. Check the label when the tee arrives, wash cold, and skip the dryer.

Price and availability

The listing shows $7.91 USD against a $8.45 original, marked in stock. The item price you pay is not the delivered price: service fees and international shipping are confirmed separately on the shopping agent's site, and shipping on a single lightweight tee will often exceed the garment cost. Ordering two or three colour codes in one shipment is the only way this price advantage makes sense.

How we would order it

Pick the code first from the image set, then the size from the chart rather than from habit, then wash it cold. The fabric, print and construction on our sample were sound for the money; the unresolved variables are fit and heat tolerance, and both are things you can control before and after checkout. If you need one guaranteed sizing answer before you commit, this listing does not provide it.
