I have to admit that mint green is one of my favourite colours. Unfortunately, it is a pastel and pastels can look a bit out of place if it’s not sunny out. However, this top is a slightly darker shade of mint and when toned down even more with brown it works for all seasons. By contrast you could pair this top with another pastel like pink or lilac to create a really bright and sunny look.
This top is from New Look and I love the chiffon and frilly style of it. It is see through so I put a brown vest top from Pennys underneath. If you were going for a brighter look then a lighter colour vest top would work better. You could also wear this top without the belt for a feminine and floaty look, but I prefer to show that I do have a waist by wearing the cincher belt.
Theses shoes are Michael Kors and you may have seen them in this previous post.
Also worth noting than you could always pop a cardi on for extra warmth, like this one from Pennys.
