It's not often Deadgoodundies has a full-on sale across all brands but summer discounts have just been announced – with up to 70% off some goodies. The DGU sale encompasses the best brands in men's underwear, male swimwear, night and loungewear, t-shirts, vests and tops, long johns, thongs, briefs, boxers and so much more. Founder Adam Davies offers his top tips for shopping the sale today:

# 1 Shop early if you wear size medium or large - they sell out fastest. (XS, S and XL guys are in for a treat)

# 2 If you have a favourite collection shop by brand – you can also filter by size, colour and fabric.

# 3 Sale stock is always limited – they might be the last few left, the very, very last one on the shelf, an end of line or discontinued ranges but everything is genuine, original stock on DGU.

# 4 Not shopped that brand before? Always check the size guide for your waist/chest measurement because different collections have different measurements for XS, S, M, L, XL etc.

# 5 Some brands won't be back on DGU, for example Body Art is no longer produced so if you like it, shop now. Check out Boglietti, SAXX, Eppure Luca, Nils Bohner, Pull-in, Pikante, Clever and Bum-chums because when these are gone, they're gone for ever from our website.

# 6 Push the boat out! If you always wear black or white, buy colour. Get that thong or the long johns you've hesitated over, shop with an open mind and try a new brand, a new shape, a different fabric…

# 7 Get lucky. Success starts with good underwear. Interview? Date night? Romantic weekend away? Proposal? Wedding day? Or just because it's Wednesday. Treat yourself to something special.
