Lots of discount codes this week – but first, here’s our favourite bargainista tip. This season’s essential accessory is free, according to the Evening Standard: yes, all you need is a smile. Even Anna Wintour has been at it.

• There’s plenty to smile about in this week’s Grazia, with coupons including Guess, Lee, Warehouse (quote GRAZ1009 at checkout until 21 October) and Wallis (quote GECW10 online).
• Save 20 per cent at LK Bennett with code RED9 until 3 November.
• Save 15 per cent at Frockonline with code CMFROCK10 until 30 November.
• There’s 15 per cent off vintage-inspired fashion at Tara Starlet with code HANDBAG until 1 November.
• Snap up a stupendous bargain at koodos this week, with further reductions including men’s and women’s jeans from just £15.

Nope, we haven’t counted the number of shopping days left until you-know-when… but if you are contemplating getting a few presents on your list crossed off early, then this is the sample sale for you.

The TSE sale is always worth a look for classic men’s and women’s cashmere, as well as fashion-forward pieces. Personally, I’m hoping for cold snap so that I can wear my black cashmere cape from last year’s sale.

The sale is on 20 and 21 October (10am to 8pm) and 22 October (10am to 6pm) at the Camden Centre, Bidborough Street, London WC1H 9JE.

And if you can’t make it down there, check out the bargain cashmere selection at koodos, including Dear Cashmere and Basso & Brooke.

We do like an investment buy at Bargainista – and designer denim certainly falls into that category.

It was slightly alarming, however, to read in the Daily Mail that up to two million of us hold onto a favourite pair of jeans for up to forty years, with the average pair of British jeans clocking in at six years old.

Above, here are a few pairs available at tasty discounts that you might want to hang on to, from William Rast, J Brand and Superfine. In the meantime, let’s see how bargainistas compare to the national average.

Paris Fashion Week draws to a close on Thursday, which means that’s it from the catwalks for another season. Here are a few bargainista suggestions for adding a little je ne sais quoi to your wardrobe for less.

• French polish is a key look this season; see the new collection from Next for a high street take on the trend.
• A pink coat is the thing to cheer you up, notes this week’s French Elle. Take your pick from Dotty P, Hobbs, New Look and Monsoon.
• Hussein Chalayan had his moment in the Paris spotlight yesterday; check out our selection at koodos with an extra 10 per cent off.
• More Paris brands from koodos: Yves Saint Laurent’s animal print bag; Stella McCartney sunglasses from £29; Cacharel watches.
• Chanel tomorrow. If you do one thing, as they say, to update your make-up this autumn, make it a black lippie – yes, really. Chanel’s Rouge Allure (£21.50 from Boots) in Maniac, Hysteria and Obscure leads the pack.
