Article: Best Times to Go Shopping for Clothing

Shops usually rearange and replenish their racks on Thursday evenings ready for the weekend rush. They also mark down sale items at this time as well. So look for shops open on Thursday evenings to beat the sales rush and get the best bargains. If there are no shops open at that time nearby then try for as early as you can on Friday mornings.

If you are after the latest season styles try and wait 6 to 8 weeks into the season when a lot of items will be marked down.

Stock up on classic styles at the end of season when prices should have been reduced to make way for next seasons new stock.
The new season usually begins about two months before to the official change of season (ie winter, spring summer and autumn).
