Use their sizing guidance to avoid dissapointment...
Ordered two garments from Olderbest on the 25th of April. On the 29th I received an email suggesting I verify my size selection. I sent them my measurements and weight etc and they replied within 12 hrs suggesting I go an additional size up. They arrived this morning 7 May. They got it right. Items fit perfectly. Quality for the price is outstanding. Both items are really heavy weight cotton and feel like they will last for ages. I bought a McCoy's hoodie for over £200 a few years back. This feels as good, if not better, for under a quarter of the price. Amazing.
