Stored after being worn several times. This is a checked vintage shirt believed to be from the late 1990s to early 2000s. The fabric is 100% cotton. Shoulder width: Approximately 40cm (flat measurement) Length: Approximately 71cm Sleeve length: Approximately 60cm Underarm circumference: Approximately 41cm (flat measurement) The "LAUREN" line features a cut designed for women's figures, but those from the 90s and 00s were relatively loose-fitting, so men also wore them as unisex items. Evidence for dating: • Tag design (commonly known as the green tag) The "LAUREN" line was launched in 1996. This dark green tag with white lettering was a standard design used from the late 90s to the early 2000s, during the brand's early years. • "LRL" monogram embroidery The logo combining "L", "R", and "L" on the chest was frequently used in the Lauren line during this period. The fact that it's not the Polo Player (horse) logo also symbolizes the uniqueness of the women's line. • Country of manufacture and specifications The tag says "MADE IN THAILAND." After the 1990s, Ralph Lauren began to shift its production base to Asia, and Thai-made items were very common during this period. • Shape of the material and size tag The specification of a long tag with the size (S) and material information attached under the main tag is also a pattern often seen in products from the late 90s to the early 2000s. • Chest flap pockets The style with double pockets with flaps incorporating elements of work shirts and military shirts, and with red monogram embroidery, is a representative design from the early to mid-period of the "LAUREN" line, which was launched in 1996. • The waist is not extremely cinched, and the silhouette is close to a boxy shape with room in the body width relative to the sleeve length and length. This is a characteristic of the period when the "relaxed fit" was prioritized over current trends. • Button specifications Simple four-hole plastic buttons without any engraving, with a slightly concave center, are standard specifications for Ralph Lauren flannel shirts from the 90s to the 00s. • In recent models, there are more buttons with the brand name engraved on them, but this plain type is a characteristic of vintage items from that time.
