* FTSE 100 down 0.1%, FTSE 250 off 0.4%

Sept 26 (Reuters) - London stocks extended declines from the previous session on Tuesday as worries of tighter macro conditions dampened sentiment, while fashion retailer ASOS hit a more than two-month low after reporting grim results and outlook.

ASOS fell 1.5% as the online fashion retailer reported a 15% decline in fourth-quarter sales and said second-half earnings were expected to be around the bottom of its guided range.

Broadly, the internationally-focused FTSE 100 dipped 0.1% as worries about interest rates staying elevated for longer lingered.

The more domestically-oriented FTSE 250 shed 0.4%, weighed down by a 4.3% loss in Close Brothers. The banking firm said its financial results for the full year were significantly impacted by provisions in relation to Novitas.

In a bright spot, A.G. Barr added 2.7% after the Irn-Bru maker posted a rise in its first-half profit, helped by strong demand for its cocktail mixes, soft drinks and price hikes of its products. (Reporting by Johann M Cherian in Bengaluru; editing by Eileen Soreng)
