T.M. Lewin vs UNTUCKit: which dress shirt is actually worth it?
Side by side on the specifications that decide how a shirt looks after a year: the collar interlining, how the size is arrived at, the cloth, and the price each brand actually advertises rather than the one on the ticket.
T.M. Lewin delivers more shirt per dollar than UNTUCKit
T.M. Lewin scores 41/100 on specification per dollar against 0/100 for UNTUCKit. The score weighs two things a shirt is actually judged on after a year: the collar interlining and how the size is arrived at. UNTUCKit does not publish its collar interlining, so there is nothing there to check. Price is the lowest per-shirt figure each brand advertises itself, not a list price neither of them expects you to pay.
- Lower advertised price: UNTUCKit — $79 against $86 a shirt
- Fit control: T.M. Lewin — Neck + sleeve length against alpha sizing (s/m/l/xl)

| Cloth | Twill, poplin, oxford, herringbone, dogstooth and dobby, mostly cotton with some wool blend, in both non-iron and easy-to-iron finishes.

No weave name, weight, ply or yarn count is published. The wrinkle-free line is framed as resisting creasing rather than as a graded non-iron finish.45 |

Who each one is for
- T.M. Lewin
- Someone who wants to know in inches what a brand means by "slim" before ordering, and is buying four shirts to trigger the discount.
- UNTUCKit
- Someone whose whole problem is shirt length, not collar construction, and who wants a wrinkle-free shirt they never tuck in.
Questions people ask about this pair
- Is T.M. Lewin or UNTUCKit cheaper?
- UNTUCKit. Its lowest advertised price is $79 a shirt against $86 for T.M. Lewin. At full list the two are $115 and $115.
- Which has the better collar?
- Neither can be separated on published evidence. Does not publish whether the collar and cuffs are fused. Nothing on the shirt listing or the size guide addresses interlining. Does not publish whether its collars are fused. Collar shape is offered as a filter — button down, camp, point, semi cutaway, spread — and nothing about interlining appears on any page read.
- How do I get the right size from T.M. Lewin or UNTUCKit?
- T.M. Lewin: Formal shirts are sold by collar size and sleeve length across a 14.5 to 20 inch collar range, and T.M. Lewin is the rare brand that publishes the garment chest and waist behind each fit name. At a 15.5 inch collar the four formal fits run Regular 47 inch chest and 44 inch waist, Slim 45 and 40, Fitted 43.5 and 38.5, Super Fitted 41 and 37 — six inches of chest and seven inches of waist from end to end. The casual Relaxed fit switches to alpha sizing, so the brand runs two sizing systems across one shirt range. UNTUCKit: Alpha sizing only, Small through XXX-Large, crossed with Slim, Regular, Relaxed, Tall Slim and Tall Regular and a sleeve length choice. There is no neck-and-sleeve sizing and no made-to-measure; the whole size system is built around shirt length rather than collar.
- What are the return policies?
- T.M. Lewin: Thirty days from order confirmation, unworn and with tags on. The customer pays: the prepaid label price and any taxes and duties are deducted from the refund. There is no exchange at all — the policy requires you to return the shirt and make a separate new purchase. Altered items cannot be returned. UNTUCKit: Thirty days from delivery for unworn, unwashed, undamaged items, exchanges included, and a prepaid return label is provided so the brand pays return shipping. A third-party return guide states a 60-day window; the brand’s own support pages say 30 and the two disagree.
What a made-to-measure shirt costs from the workshop
We are not on this page to sell you a third option you did not ask for, so here are the numbers to compare against the table above. A shirt cut to your own measurements in our Hoi An workshop is $39–$59 garment-only, depending on the cloth, with shipping quoted separately. There is no size to pick and no fit name to guess between: the pattern is drafted from your measurements.
Neither T.M. Lewin nor UNTUCKit is a bad shirt at its price. The question this page exists to answer is what each one publishes about how it is built — and that is in the table, with the sources. See how the measurements are taken.
“I’m incredibly grateful for the Team at Nathan Taylor’s, I had the absolute best experience from the WhatsApp video call to the customer service… they are top notch. I can’t recommend them enough and will definitely be purchasing more suits from them. Cảm ơn!”
“Suit arrived! It’s incredible, amazing job thank you.”
“Ordered two suits and four shirts, remotely from the US. They fit great and are great quality! Was able to do everything over WhatsApp for measurements, etc. Will definitely visit if I ever make it to Hoi An. Highly recommend!”
“Being a short and stocky person, I could never truly get clothing that fitted properly. "Off the rack" was never an option... As I opened the small box, I got nervous and wondered if I made a big mistake and basically gambled away a fair amount of money. I ordered a 3 piece suit, 2 shirts and had a pair of leather dress shoes. Everything fitted nicely... the shirts were absolutely PERFECT.”
“Very satisfied; incredibly skillful to make clothes fit so perfectly. Beautiful fabric exactly as promised, very neat — would simply love to order from here again!”
“They did such an amazing job, my suit fits perfectly and the craftsmanship is superb! Linda was a great help and she knows exactly what she is doing. I can't recommend this place enough and I will be getting more suits from them in the future guaranteed!”
“Great place to get perfect suit, they send me to Poland with no problems.”
“WOW! Ordered a suit online with Linda. She contacted me by video call to go through the measuring process and once confirmed measurements again, around 4 weeks later a made to measure suit arrived in the UK. Fitted perfectly and I didn't even visit! Fantastic quality and customer service from Linda. Would definitely recommend!”
“Exceptional experience from start to finish. I ordered a fully custom two-piece double-breasted suit remotely from France, Linda and Jennifer guided me through every step with patience and professionalism. The suit arrived in under 3 weeks and the result is flawless: fabric, cut, lining, silhouette, everything is perfect. Nathan Tailors delivered exactly the vision I had in mind. I will absolutely be ordering again. Highly recommended.”
“This was my first time buying suits online so I was a bit apprehensive. However, the online order form was both easy to use and very thorough, and they did a video call with me to make sure of a couple of measurements that were out of the normal range. Two suits and a shirt arrived here in New Zealand in less than two weeks, are well-made, and fit perfectly. I'm thrilled with the service.”
