What our customers say
Nicola S.
Delivery was late, service was excellent!
My parcel arrived a few days later than expected which was frustrating, hence four stars. But I can't fault OffSEASON themselves. They replied quickly, explained what was happening and followed up. I'd still order again.
Sarah W.
Small issue, handled really well
I accidentally put my old address on the order and only noticed afterwards. Sent a slightly panicked email and they changed it before dispatch. Thank you again, Cherry! Love this dress so much!
Eilidh M.
Made the exchange so easy
The dress was lovely but I needed a size down. I contacted customer service and they explained exactly what I needed to do. No back and forth or fuss. My replacement fits perfectly.”
Charlotte H.
Lovely, but size down if between sizes
Really pleased with it. I'm usually between an 8 and 10 and ordered the 10, but I could probably have gone with the 8. I kept it because I actually like the slightly looser look. Everything else is exactly as pictured.
Fiona M.
Looks just like the photos
I’m always slightly suspicious ordering clothes online because colours and fit can look completely different in person. The jumper genuinely looks like the pictures.
Bethan J.
So refreshing
I emailed on a Sunday evening expecting to hear back sometime during the week and had a helpful response much sooner than expected. Friendly, straightforward and no copy-and-paste nonsense.
Sophie W.
True to size for me
I ordered my usual size 10 and wouldn’t size up or down. There’s enough room through the waist and hips and it doesn’t pull anywhere when I sit down.
Sophia M.
What!!
"It felt expensive. I checked the price three times because I didn't believe it. And it's not too tight. OffSEASON has so many loose-fit designs to choose from. Love it!"
Isabella N.
Exactly what I needed
"I've ordered every summer for four years. Nothing has ever disappointed me. My size sold out before I could check out last time -I set a reminder this season."
Ella S.
Comfortable and stylish
"Wore the brown dress to a wedding, a picnic, and a festival. Same dress. Three completely different looks. Worth every cent at full price, at this discount it's almost criminal."
Heather S.
Good Quality
"The quality is noticeable. Had a linen pants set and they held up well after a few washes, which is always a plus. And I am happy to support their business, two best friends founders".
