Product Insights
Mosaic Shirt Modern Fit 59 CAD Modern fit hugs the body with fitted shoulders and narrow sleeves, sitting between Le 31's Slim and Standard/Comfort cuts. Fabric is 97% organic cotton and 3% spandex. Cotton-rich shirting wrinkles fairly easily but is generally durable for everyday wear; the 3% spandex adds give, not wrinkle resistance. Buyers rate value highly, with one calling it a very pretty shirt with an excellent quality/price ratio.
Verified claims
- fit
- Modern fit hugs the body with fitted shoulders and narrow sleeves, sitting between Le 31's Slim and Standard/Comfort cuts.
- sizing
- MEDIUM is cut for a chest of 96.5–101.5 cm (38–40 in) and a natural waist of 81.5–86.5 cm (32–34 in).
- sleeve_fit
- Narrow sleeves are described by buyers as a real improvement, but the slimmer cut limits movement while reducing underarm wrinkles.
- shoulder_fit
- Shoulder seam should meet the armhole at the end of the shoulder bone; too long extends onto the arm, too short causes the sleeve to pull.
- fit_notes
- One buyer reports the shirt fits well and looks neat on a larger midsection, though a minority note says the arms run long.
- material
- Fabric is 97% organic cotton and 3% spandex.
- fabric_behavior
- Cotton-rich shirting wrinkles fairly easily but is generally durable for everyday wear; the 3% spandex adds give, not wrinkle resistance.
- comfort_drape
- Cotton shirting is breathable and comfortable in warm weather; the medium-weight weave gives a structured, matte, usually opaque drape.
- care
- Machine wash, do not bleach, do not soak, hang to dry, iron with or without steam; wash dark colours separately.
- collar_styling
- Button-down collar works with a suit or open without a tie, its roll sits neatly under a sweater, and unbuttoned points should look effortless rather than fussy.
- construction
- Construction includes a back yoke, center back pleat, curved hem, button placket and single-button barrel cuffs.
- pattern
- All-over dense mosaic print repeats across body, sleeves and collar in a uniform grid.
- colorways
- Available in Patterned Black, Patterned Blue, Indigo/Dark Blue and Burgundy; Indigo/Dark Blue is the only colorway not named 'Patterned'.
- variant_selection
- Every colorway carries the full SMALL–XX-LARGE ladder at the same 59 CAD, all 20 size-color combinations are in stock, and Patterned Black is the colorway represented in listing photography and reviews.
- value
- Buyers rate value highly, with one calling it a very pretty shirt with an excellent quality/price ratio.
- styling
- The contemporary mosaic print is described as good-looking, versatile and easy to wear across occasions.
- use_cases
- Reviewers see it working for smart-casual office outfits, casual evenings and budget wardrobe refreshes.
- shipping
- One buyer reports an online order placed Dec 18 had not arrived by Dec 28 despite a pre-Christmas delivery guarantee.
- stretch_test
- To judge stretch, 10 cm of fabric that stretches to 12 cm indicates about 2 cm of give.

Product comparison
Compared within this brand.
| Mosaic Shirt Modern Fit: Choose this if you want a body-hugging modern fit with fitted shoulders and narrow sleeves for smart-casual office looks, where reviewers found the versatile print pairs well with tailored neutral pieces. It's cut in a 97% organic cotton, 3% spandex stretch weave with a button-down collar, single-button barrel cuffs, and a curved hem that's longer at front and back, offered in four colors from Patterned Black to Burgundy in sizes Small through XX-Large. Note that photos showed the rear view sitting over the hips with a relaxed look and slight pull lines at the lower back and sleeves, so the fitted cut may not suit those wanting a looser drape.[1,2] | Geometric Mini-Pattern Shirt Modern Fit: Choose this if you want a short-sleeve button-down with a body-hugging modern fit, featuring fitted shoulders, narrow sleeves, a button-down point collar, and a curved hem. It is made of 100% organic cotton and comes in white or blue with an evenly spaced mini geometric pattern, in sizes Small through XX-Large. Note that the XX-Large size is listed only in the White color, not in Blue.[3,4,5] | Floral Tapestry Shirt Modern Fit: Choose this if you want a short-sleeve, modern-fit shirt cut to hug the body with fitted shoulders and narrow sleeves, made from 100% organic cotton. It features a dense all-over small floral print, a button-down spread collar, and a central button placket, and is an exclusive Le 31 design from Simons, designed in Canada. It comes in Assorted, Patterned Blue, and Turquoise colorways from SMALL to XX-LARGE, though the left-chest pocket is only faintly visible against the print.[6,7] |

How do I review if I haven’t received them
I still have not received the items so I’m not sure how you expect me to rate them. I ordered online on Dec 18 and your website guaranteed before Christmas delivery yet here we are Dec 28 without the items. Horrible service
A winner!
Good-looking print, versatile but different. The narrower sleeves are a real improvement on the traditional fit. Even though hubby has a paunch, this shirt fits well and looks neat.
Fit weird
Arms too long
