Greece indeed participated in the 2014 FIFA World Cup, reaching the Round of 16. This is a significant event to mention....
**Revised Attempt (aiming for ~220 characters):**
The Greece 2014 training shirt by Nike was worn during the season the team participated in the 2014 FIFA World Cup. It features a blue body with a dark blue round neck collar. The design is completed by contrasting two-toned sleeves in dark and light blue, along with light blue shoulder and side panels.
Character count: 297 - still too long. I need to simplify.
Let's try to combine sentences and remove unnecessary words.
"The Greece 2014 training shirt by Nike was worn during the season the team participated in the 2014 FIFA World Cup. " (133 characters)
"The shirt features a blue body with a dark blue round neck collar, complemented by two-toned dark and light blue sleeves, and light blue shoulder and side panels." (171 characters)
Combined but still two sentences. Total 304 characters. I need to cut more.
Let's try:
"The Greece 2014 training shirt by Nike was worn during the season the team participated in the 2014 FIFA World Cup. The blue shirt features a dark blue round neck collar and striking two-toned sleeves in dark and light blue, with matching light blue shoulder and side panels."
Characters: 279. Still too long.
Let's cut "during the season the team participated in".
"The Greece 2014 training shirt by Nike, worn for the 2014 FIFA World Cup, features a blue body with a dark blue round neck collar. Contrasting two-toned sleeves in dark and light blue, along with light blue shoulder and side panels, complete the design."
Characters: 271. Still too long.
Let's try to make it 2 sentences, maximum 250 characters.
"The Greece 2014 training shirt by Nike was released for the season the team competed in the 2014 FIFA World Cup. This blue shirt features a dark blue round neck, complemented by two-toned dark and light blue sleeves, and light blue shoulder and side panels."
No, I cannot use "This blue shirt". It has to be "The blue shirt".
"The Greece 2014 training shirt by Nike was released for the season the team competed in the 2014 FIFA World Cup. The blue shirt features a dark blue round neck, complemented by two-toned dark and light blue sleeves, and light blue shoulder and side panels."
Characters: 276. Still too long.
I need to drastically cut down the design description or the intro.
Maybe I can remove 'round neck collar' and just say 'round neck'.
"The Greece 2014 training shirt by Nike, worn during the 2014 FIFA World Cup campaign, features a blue body with a dark blue round neck. Complementing the design are two-toned dark and light blue sleeves, alongside light blue shoulder and side panels."
Characters: 257. Closer. Let's try to shave off a few more.
"The Greece 2014 training shirt by Nike, worn during the 2014 FIFA World Cup campaign, features a blue body and a dark blue round neck. Complementing the design are two-toned dark and light blue sleeves, alongside light blue shoulder and side panels."
Characters: 253. Still slightly over.
Let's try to rephrase the second sentence to be more compact.
"The Greece 2014 training shirt by Nike, worn during the 2014 FIFA World Cup campaign, features a blue body and a dark blue round neck. Its design is accented by two-toned dark and light blue sleeves, and light blue shoulder and side panels."
Characters: 249. Perfect!
