A: Yes, it's the same thing. ON amazon you can find all kinds of wonderful substitutions. 3X, 3XL, XXX-Large and probably some more creative representations too.
A: 3X means that the waist circumference is three times that of large and tall means just about anything, but will work really well if the guy is 6'5""! The 3X waist will fit a 52" waist (Plus). My waist is 42 and a large performs quite nicely.
A: 3x big is for thicker/wider people.
plus-sizes XL - 4XL+
If you look for waist measurements with your sizing (as is often the case in "menswear") here's how how we categorize those sizes: XL (44 & under), 2XL (46-48), 3XL (50-52), 4XL (54-56), 5XL (58-60), 6XL (62-64).
A: They are the same.
Finding the Perfect Plus Size Fit. 1X. (18W-20W) 2X. (22W-24W) 3X. (26W-28W) 4X.
A: No. XXL is Misses, 42 I believe. 2X is Plus size, 44.
3X-Large – Design width no bigger than 13 – 14 inches. 4X-Large – Design width no bigger than 13.5 – 14.5 inches. Standard T-shirt Width for Youth Classic Tees. Extra Small – 16 inches.
An XXL is a Misses 18. A 1X is a plus size 14/16. The difference is that plus size clothing is generally made wider and with more room in the arms, hips, thighs, butt, and stomach areas.
